The refractoriness is the characteristic of the high temperature resistance of the material. Raw materials such as mullite, kyanite, andalusite and sillimanite need to be tested for their refractoriness during use to understand the purity of the raw materials. For example, impurities, especially those with strong flux function, will reduce the refractoriness.
