Measurements of physical properties of glasses, melts, and other materials
L.G.P. provides precise measurements of physical properties of glasses and
melts, which are used as input data for modeling and optimization. The
measurements are performed using precision analytical instruments.
The list of testing services includes:
Absorption spectra of glasses, and melts in the temperature range
20 ÷ 1650°C. Wavelength range from 0.4 to 8.0 μm;
High-temperature spectral emissivity, and reflectivity of different materials;
Radiative thermal conductivity (up to 1650°C);
Density of glasses, and melts within the temperature range
20 ÷ 1650°C;
Electric conductivity within the temperature range
300 ÷ 1650°C;
Viscosity of glasses, and melts within the range of Log (η, Pois) from 1.0 to
15.0 at temperatures up to 1650°C;
CTE of solid, and viscous materials (up to 1200°C);
Characteristics of structural, and stress relaxation in inorganic materials;
Visco-elastic characteristics of composites, and seals;
Phonon (true) thermal conductivity of glasses, and melts (up to 1650°C);
Mechanical properties, such as elastic modulus, tensile strength, and hardness.
