Kyanite is a new type refractory material, which is aluminous mineral with pale blue or cyan color, light gray. Hardness 5.5-7.0, specific gravity: 3.53-3.65.
Kyanite has Strong resistance to chemical corrosion, high mechanical strength and thermal shock, thermal expansion is not reversible. Kyanite is the main material for the production of amorphous materials and furnace top brick, phosphate unfired brick, mullite bricks, low creep brick.

Application of Kyanite:
Kyanite is Used to make excellent senior refractories, refractory mortar, cement and corrosion casting products, plastic and ramming mixes. Kyanite is also an expansion agent, especially for Al2O3.SiO2 refractory, due to high alumina bauxite and other impurities in the Fe2O3, TiO2, RO, R2O and other effects, and due to uneven uniform composition of ingredients, often caused by material shrinkage after burning Large, so the use of kyanite as a bulking agent can overcome the high temperature and cooling process in the contraction of cracks, peeling and thus affect the service life.
