Characteristics of a refractory mineral neutral, neutral refractory structure, chemical composition neutral refractories (Sericite) is a natural fine brick, is a subspecies of brick, fire-resistant layered silicate structure material sales, structure composed of two layers of silicon-oxygen tetrahedron double layer of silicon oxide formed octahedral aluminum sandwiched. Cleavage completely, can be split into very thin sheets, film thickness up to 1u below (theoretically be whittled 0.001u), radius to thickness ratio; compared with brick: a natural small particle size refractory, easy processing Ultrafine features. Neutral refractories crystal chemical formula: K0.5-1 (Al refractory species, Fe, Mg) 2 (SiAl) 4O10 (OH) 2 nH2O, general chemical composition:? SiO2 43.13 ~ 49.04%, Al2O3 27.93 ~ 37.44% , K2O + Na2O 9 ~ 11%, H2O 4.13 ~ 6.12%. Development and utilization of the status quo and development trend of siliceous 1. Exploitation Situation, Problems and Countermeasures of the main application areas are building materials siliceous and abroad, about half of the silicon consumption. Siliceous country has a certain status in the world, currently by output ranks third in the world, siliceous up more than 50 mines and processing plants. Siliceous our annual output has reached 100,000 t, accounting for 12.5% ??of world production, domestic consumption of 60 000 t of refractory Which is good, export 40,000 t, as long as all the normal siliceous ore production to meet demand and exports.
