Research of phase structure at various temperatures of roasting of the ceramic brick on basis of easily fusible clay and waste products of manufacture
Researches have shown, that at roasting a ceramic brick on the basis of polymineral fusible clay, ashes slag a material and salt waste products from secondary processing including aluminium slags and breakage mullyte is formed at 1000оС. At rise in temperature of roasting of a brick up to 1100оС mullyte has short prisms crystals that is connected to the high maintenance in raw materials Fe2О3, thus Fe3+ replaces Al3, that results in the limited isomorphism.
