Kyanite Mineral in Powder Form ensures high resistance to thermal shock. The Kyanite Mineral also decomposes into high strength phase mullite at a relatively low temperature ranging from 1350 - 1375 degree celsius, there by inducing faster sintering. The Kyanite Mineral is available in aluminium-rich metamorphic pegmatite or sedimentary rocks. Kyanite Mineral in Powder Form is strongly anisotropic, in that its hardness varies depending on its crystallographic direction.
