Density
Density is the mass of a material per unit volume. The unit of measurement can be expressed in different ways and is referred us as g/cm3 but another measurement value is kg/m3.
Thermal Conductivity
Thermal conductivity measures how easily heat is transmitted through a material. There is a growing specialist market for advanced ceramics use in applications with high thermal conductivity requirements.
Flexural Strength
Flexural strength, also known as bending strength, modulus of rupture or transverse rupture strength, is defined as the maximum stress in a material just before it yields in a bending test
