Ontology Specification Draft

Abstract

The GlasDigital Ontology was developed for the GlasDigital project (https://www.materialdigital.de/project/4). It describes the robotic melting process at Bundesanstalt für Materialforschung und -prüfung (BAM), Berlin and also contains the terminology of the SciGlass database (The data has become open source since 2019. See: https://github.com/epam/SciGlass). A practical use case of the ontology is the Semantic Knowledge Base (SKB) developed with Fast Ontodocker (https://git.material-digital.de/ya-fanchen/fast-ontodocker), which covers the entire glass manufacturing process parameters and glass property searching, as well as the integration of SciGlass data. It is based on the PMD Core Ontology (PMDco) v1 and a migration to the latest PMDco is planned.

absorbancec back to ToC or Class ToC

IRI: https://glasdigi.cms.uni-jena.de/glass/Absorbance

In optics, absorbance or decadic absorbance is the common logarithm of the ratio of incident to transmitted radiant power through a material, and spectral absorbance or spectral decadic absorbance is the common logarithm of the ratio of incident to transmitted spectral radiant power through a material. Absorbance is dimensionless, and in particular is not a length, though it is a monotonically increasing function of path length, and approaches zero as the path length approaches zero. The use of the term "optical density" for absorbance is discouraged.

activation energyc back to ToC or Class ToC

IRI: https://glasdigi.cms.uni-jena.de/glass/ActivationEnergy

This term is used to describe the amount of energy necessary for an atom, vibrating in the vicinity of a certain position in a glass-forming network, to acquire to surpass a potential barrier surrounding it and move to another position. When a group of atoms can form two or more stable configurations, the energy of vibrations needed for this group of atoms to change from a certain configuration to another is also called the activation energy. Activation energy can be determined by the temperature dependence of a property whose value is directly connected with surpassing potential barriers by atoms or ions of glass. These are the so-called transport properties.

IRI: https://glasdigi.cms.uni-jena.de/glass/StressOpticCoefficient

Ideally, homogeneous glass is isotropic. However, at the presence of non-hydrostatic stresses it becomes non-isotropic. It means that perpendicular vibrations of a non-polarized light are going through the glass sample with different velocities. Accordingly the sample is characterized by two different refractive indexes (develops a double refraction). A constant which shows correlation between the optical path difference between vibrations along two perpendicular axes (with minimal and maximal velocities) and stresses which gave rise to this difference is called the stress-optic coefficient, or Brewster's constant.

The relative permittivity (in older texts, dielectric constant) is the permittivity of a material expressed as a ratio with the electric permittivity of a vacuum. A dielectric is an insulating material, and the dielectric constant of an insulator measures the ability of the insulator to store electric energy in an electrical field.

dilatometric softening temperaturec back to ToC or Class ToC

IRI: https://glasdigi.cms.uni-jena.de/glass/DilatometricSofteningTemperature

The temperature at which the length of a sample in a dilatometer, with considerable external force applied to the sample in the course of heating at constant rate, reaches a maximal value and begins to decrease with further increases in temperature. The appearance of the maximum on the dilatometric curve is connected with the parallel influence of sample dilatation with increasing temperature and sample deformation due to the viscous flow. The position of the maximum can correspond approximately to a certain viscosity of the studied glass. Usually this viscosity is assumed to be equal to 10^11 P. However this value depends a great deal on the external load applied to the sample (the greater the load the higher corresponding viscosity), on the area of sample section (the greater the area the lower viscosity), on the value of TEC for the studied substance in its liquid state (the higher TEC the lower viscosity), on the rate of heating and on the previous thermal history of the sample (the higher the heating rate the lower viscosity; the lower the fictive temperature of the substance the lower viscosity). Thus the actual viscosity values at dilatometric softening temperatures could differ from the value stated above as greatly as one order of magnitude.

Glass is an inorganic product of fusion which has cooled to a rigid condition without crystallizing. [Standard definition (ASTM; C162-52)] Note: In recent years there has been a definite tendency to broaden the meaning of the term glass and have it cover all kinds of non-crystalline solids {see for example (Varshneya, 1994: References)}. However, in SciGlass the definition of ASTM is strictly followed. All information presented in this Information System concern the properties of non-crystalline solids cooled to a rigid condition from temperatures higher than the glass transition region or the properties of glass-forming melts.

glass transition regionc back to ToC or Class ToC

IRI: https://glasdigi.cms.uni-jena.de/glass/GlassTransitionRegion

The temperature range where the temperature dependencies of properties of a glass-forming substance, which are specific for a liquid state, transform gradually into temperature dependences of properties specific for a glassy state. As a convenient and theoretically reasonable approximation it is possible to determine the width of the glass transition region by the width of a hysteresis loop obtained for the same cooling and heating rates and for the same property. A deficiency of this approach is the fact that the borderlines of hysteresis loop depend on the precision of measurements of the corresponding property. However, in the most cases, it is not essential to know exact positions of the boundaries of the glass transition regions and the method mentioned above is quite acceptable. Position of the glass transition region for any selected glass-forming substance depends of the rates of temperature change and, to a certain extent, on the selected property.

Thermodynamically stable (above liquidus temperature) or metastable (below liquidus temperature) state of a non-crystalline substance. It should be noted that this thermodynamic definition of liquid state does not agree with the most common definitions of liquids as substances, the main characteristic of which is the fluidity. According to the thermodynamic definition a liquid could be thoroughly rigid (for example, after a very long isothermal hold, a glass-forming substance can reach a metastable state at viscosity of 10^15 P or higher). In the present Information System, the thermodynamic definition of the term liquid state is used.

IRI: https://glasdigi.cms.uni-jena.de/glass/Microhardness

The characteristic of the deformation of the glass surface under the influence of a pyramidal diamond indentor. The size of indentation is usually of the order of several micrometers. In the most cases two kinds of pyramids are used, namely Vickers and Knoop pyramids. The Vickers hardness number (VHN) = 1.8544F/D kgf/mm^2 where F is the force in kgf and D is the average diagonal of impression in mm. The Knoop hardness number (KHN) = 14.23F/L kgf/mm^2 where L is the length of the long diagonal. The difference between values obtained by these two kinds of measurements is not great and usually is within the limits of the scatter of data reported by various authors for the same glass composition. Thus in the Auxiliary Database all microhardness data are presented together independently on the kind of indentor used for the corresponding measurements. In Sciglass database, unit = GPa

IRI: https://glasdigi.cms.uni-jena.de/glass/RelaxationTime

Relaxation is the process of moving to equilibrium for a system driven out of equilibrium. Relaxation time t is a constant characterizing the speed of this moving. In the simplest case when the relaxation of the system can be described by only one relaxation time and this value does not change with time during the whole relaxation process.
