Thermal shock - Wikipedia
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. Thermal shock resistance measures can be used for material selection in applications subject to rapid temperature changes. A common measure of thermal shock resistance is the maximum temperature differential, $${\displaystyle \Delta T}$$, which can be sustained by the material for a given … See more Thermal shock is a phenomenon characterized by a rapid change in temperature that results in a transient mechanical load on an object. The load is caused by the differential expansion of different parts of the … See more Thermal shock testing exposes products to alternating low and high temperatures to accelerate failures caused by temperature cycles … See more • Biot number • Impulse excitation technique • Spontaneous glass breakage • Strain See more Borosilicate glass is made to withstand thermal shock better than most other glass through a combination of reduced expansion coefficient and greater strength, though fused quartz outperforms it in both these respects.
