Thermal shock parameters of ceramics evaluated by infrared radiation heating

摘要

An infrared radiation(IR) heating method was used to evaluate thermal shock parameters(thermal shock strength and thermal shock fracture toughness) of float glass and alumina. This technique makes it possible to evaluate the parameters directly from the electric power of the IR heater. In this paper we discuss how the pertinent thermal shock parameters should be estimated both as physical properties of a material and as a function of temperature.
