Bulk Buy White Fused Alumina Micro Powder Italy

Refractory materials refer to natural and synthetic high temperature resistant mineral materials(brown fused aluminum oxide). According to chemical properties, refractory materials can be divided into acid refractory materials, alkaline refractory materials and neutral refractory materials. Pyrophyllite is the main component of the ore, also known as pyrophyllite(white fused aluminum oxide). Semi siliceous clay is mainly used to make semi siliceous clay products.

But the refractory raw materials are usually divided into aluminum silicon refractory raw materials, basic refractory raw materials, heat insulation refractory raw materials and other refractory raw materials(brown fused aluminium oxide). Alumina silica refractory material refers to the natural and synthetic Al2O3 and SiO2 binary system high temperature resistant mineral material. There are few semi siliceous clay resources and few uses in China(brown fused alumina manufacturer). There are many classification methods of clay.


The raw material is widely distributed in nature, and it is the largest series of refractory raw materials(arc fused alumina). The raw materials of alumina-sio system are usually classified according to the content of Al2O3 or SiO2. Silica is used for SiO2 content more than 96%, semi silica clay is used for Al2O3 + TiO2 content 15% ~ 30%, and refractory clay is used for 30% ~ 40%(white fused alumina price). It is mainly used to manufacture the immersion nozzle and long nozzle for steel casting.


Its Al2O3 and TiO2 contents are between 15% and 30%, others are oxide impurities such as iron and calcium(silicon carbide price). The fire resistance is about 1650 ℃. Because of the great change of quartz content, its loss on ignition is lower than that of ordinary refractory clay, and its heating shrinkage is smaller than that of ordinary refractory clay(white fused aluminium oxide). According to the paragenesis and mineral content of pyrophyllite, pyrophyllite ore can be divided into five natural types.


The particle size of quartz sand contained in semi siliceous clay has a great influence on the sintering performance of its products(white fused alumina). For example, when the particle size of quartz sand is less than 0.2mm, it is easy to sinter, while when it is more than 0.5mm, it is easy to loose due to the expansion of quartz sand(brown fused alumina oxide). When the total amount of impurities is higher than 5%, the fire resistance and other high temperature properties will be greatly reduced.


Also known as Shoushan stone, Qingtian stone, seal stone, etc(white aluminum oxide). Pyrophyllite has the feel of wax, which is white, light green, light green, light red and other colors. The chemical formula of pyrophyllite mineral is alsio2 or al40, the chemical composition of 4sio2 · ho is Al2O3, 28.3%, SiO2, 66.7%, H2O, 5%(white aluminum oxide blast media); the crystal structure is monoclinic, the density is 2.7-2.8g/cm; the hardness of Mohs is 1-2, and the fire resistance is 1690-1730 ℃.


In nature, it is very rare that there are two or more minerals in the form of a single pyrophyllite(white corundum). Clay is a kind of earth like mineral formed by long-term weathering of silicate rock (mainly feldspar) in nature. Clay is not a single mineral, but a mixture of various hydrous aluminosilicate minerals with a diameter less than 0.001mm. The properties of the products are between silica brick and clay brick(buy brown fused alumina). This kind of clay has poor plasticity and belongs to primary clay.
