Improved thermal-shock resistance in industrial ceramics

Thermal shock is a phenomenon often experienced in the kitchen by novice cooks unaware of the susceptibility of glass to dramatic temperature changes. If a glass casserole dish fresh from the heat of the oven is blasted with cold water, the sudden decrease in surface temperature creates an uneven temperature gradient across the material, causing tensile stresses and ultimately cracks. This same thermal-shock susceptibility impacts the lifetime of industrial ceramics.
Lee explained that in previous attempts to improve thermal-shock resistance, materials scientists changed properties of the material itself, but this is an expensive and difficult process with inherent drawbacks. "If you improve the material in one way, you sacrifice other properties," Lee said.
