Thermal expansion is a physical property of a substance (gas, liquid or solid) to modify its shape (length, area or volume) function of temperature. Thermal expansion relates with the expansion and contraction of particles in a substance function of temperature. Thermal expansion can also be regarded as a fractional change in size of a material/substance caused by a change of temperature.

The bulk density, thermal expansion coefficient and thermal shock resistance were examined. The results showed that there was a great effect of content of SiC on bulk density, thermal expansion coefficient and thermal shock resistance of mullite-bauxite castable.

the thermal shock resistance exist. This is the case of Molochite, which is a composite material made of mullite (roughly 55 %) and amorphous phase (45 %), with a specific production process that prevents the forma-tion of cristobalite. This material is therefore largely used in applications requiring low thermal expansion and high thermal shock

Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions.. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, molecules begin to vibrate and move more, usually creating more distance between themselves.
