Increasing the thermal-shock resistance of ceramics based on cerium dioxide plus additives

The use of dispersed additives to prevent the active sintering of CeO2 and its solid solutions makes it possible to obtain a thermal-shock resistant ceramic with a grainy structure.

Determining the thermal-shock resistance of ceramics by the ultrasonic method

The Riga Polytechnic Institute has developed a dense aluminous ceramic [i]. To determine the maximum working temperature we used the ultrasonic method of investigating its thermalshock resistance. The method is based on the change in the rate of dissemination of ultrasonic (US) waves in the specimens after the heating--cooling cycies at different temperatures. The magnitude of the resistance to thermal shock was characterized by the temperature at which there is a reduction in the rate of ultrasonic dissemination.

Wood burning stoves: Material selection and thermal shock testing of fired ceramic bodies

The overall design philosophy of wood-fired stoves is reviewed. The factors affecting the choice of materials are discussed and the relative merits of various alternatives considered. Detailed consideration is given to the development of an appropriate method for evaluating thermal shock resistance of ceramics for stove applications. The method proposed requires the measurement of impact strength subsequent to repeated shocks for comparison with tests on unshocked samples. Tests are described with results which show that this method can effectively discriminate between ceramics of different composition or firing temperature.
