High temperature vacuum expansion instrument is used to detect the high temperature expansion properties of solid inorganic materials and metal materials, especially corundum, refractory materials, shell and core materials for precision casting, ceramics, ceramic raw materials, porcelain mud, glaze, glass, graphite, carbon and other inorganic (organic) materials, metal products, polymer materials, providing necessary testing methods for scientific research and teaching. Through this instrument, the sample line variables, linear expansion coefficient, body expansion coefficient, rapid thermal expansion, softening temperature, sintering dynamics, glass transition temperature, phase transition, density change, sintering rate control (RCS) and their change curves can be completed. The sample can also be protected according to the user's requirements, and can be vacuumed with a vacuum of 0.1MPa.
