Classification taxonomy silica silica There are many processes can brick structure density, crystal transformation rate, degree of thermal expansion and use of the classification. (1) The process can be divided by brick cemented silica and crystalline silica types. (2) by crystal transformation rate, and can be divided into rapid transformation of silica, silica-speed conversion, slow transformation of the slow transformation of silica and silica. (3) According to the structure density of carbon brick factory into extremely dense and compact, relatively porous MgO-C agents, porous silica. (4) is divided according to the degree of thermal expansion of the low thermal stability of carbon brick physical and chemical indicators, thermal stability, high thermal stability of silica. (5) use is divided into refractories (Refractory material) with silica and iron alloy with silica. Refractory plastic composition and other monolithic refractories (Refractory material) is similar to that of a refractory aggregate and powder, binder and plasticizer, according to the requirements of different special additives can be added, such as preservatives, shrink agents, antifreeze, etc. Can plastic varieties are mainly based binder and primary materials used to classify the material, such as by combining clay binders classification can be combined with plastic, phosphoric acid can be plastic, aluminum sulfate can combine plastic, asphalt or coke can combine plastic and other resins . Material classification siliceous, clayey, high alumina, corundum, zircon stone, etc., that is refractory materials can be made of various properties of the corresponding fire-resistant plastic. However, the extensive use of fire-resistant plastics mainly aluminum silicate (clay and high alumina) can be plastic.
