Andalusite has the characteristics of high-temperature resistance. Adding andalusite in to the ingredients can control and reduce the shrinkage of refractory products at long-term high temperature.Andalusite is a common metamorphic mineral which forms under low pressure and low to high temperatures. The minerals kyanite and sillimanite are polymorphs of andalusite, each occurring under different temperature-pressure regimes and are therefore rarely found together in the same rock. Because of this the three minerals are a useful tool to help identify the pressure-temperature paths of the host rock in which they are found. It is particularly associated with pelitic metamorphi…اقرأ أكثر
