High thermal shock resistance
WebThermal shock occurs when an object is rapidly cooled from high temperature. The surface layers contract against the inner layers, leading to the development of tensile stress and … WebThermal shock resistance is critical for many refractory applications. Linings for high temperature furnaces are exposed to large temperature gradients and must have good thermal shock resistance. Refractory bricks contain many pores and microcracks.

WebThermal shock resistance is a characteristic feature of SiC. SiC material can withstand thermal shock due to the high thermal conductivity and low thermal expansion of SiC. … WebMar 20, 2024 · If the material has high heat conduction (such as metals) the physical change in size is rather even. If this is accompanied by a strong material resistant to tension, then thermal shock is not a likely result. However, on materials such as ceramics, glass, rocks and others, thermal shock is probable.
Webwhere k is the thermal conductivity (W/mK), ρ is the density (kg/m 3), and C p is the heat capacity (J/kg K). This would give the units of a to m 2 /s, as they should be for diffusivity (mass or thermal).
