Description
Technical field
The invention belongs to building ceramics technical field, be specifically related to a kind of the composite ceramics thinner building pottery formula soil and the using method thereof that are applicable to attaclay or contain attaclay.
Background technology
At present, be the mud after ball milling in Structural ceramics industry, send into spray-drying tower obtain powder, then suppress, shaping, fire.Structural ceramics industry uses multiple earth formula, is also called ceramic formula soil, as kaolin, wilkinite, and illite class, magnesium soil etc.The main component of attaclay is silicon oxide, magnesium oxide, He Shui, and its content of magnesia generally reaches 20%, and silicon oxide is generally 2.3-3.0 than magnesium oxide weight ratio, exceedes talcum and sepiolite proportion heavily.In attaclay, essential mineral is talcum and Free quartz, and the quantity of calcite is indefinite, also containing a small amount of clay mineral and magnet, the ilmenite etc. such as sepiolite, illite, chlorite, rich magnesium montmorillonite, can see pyritous small-crystalline once in a while.
Talcum raw material in attaclay is the moisture magnesia silicate minerals of a kind of tool layered struture, and chemical formula is Mg
