Objects expand and contract due to temperature changes. Its change ability is expressed by the volume change caused by unit temperature change under equal pressure, that is, the coefficient of thermal expansion. This instrument is used to detect the high temperature expansion performance of solid inorganic materials and metal materials, especially corundum, refractory materials, precision casting shell and core materials, ceramics, ceramic raw materials, porcelain clay, glaze, glass, graphite and other inorganic materials .
