Black Silicon Carbide is the product of silicon quartz sand and petroleum coke electrofused at high temperature in an electrical resistance furnace. The grains of Black Silicon Carbide are hexagonal c

Used in abrasive industry, such as consolidated abrasives, coated abrasives. It is a relatively pure product and its low iron alumina content makes it suitable for a wide range of applications. Consol

Aluminium oxide The hardness is very high, and the polished material generally does not react chemically. Alumina polishing abrasives are commonly used for polishing steel samples. However, it is not

The main reasons for the damage of gasifier furnace refractory lining are as follows. The thermal stress is too high. Due to the cooling effect of the Texaco burner cooling coil, the upper part of the

Driving and stopping too many times. In normal production, the temperature of the furnace refractory lining is high, and in the parking (especially in the case of hanging burner), due to the cooling e

The 2001 electronic industry standard SJ/T11260-2001 of the People's Republic of China gives the tolerance range of the diameter, flatness and roundness of the ceramic casing of the vacuum switch

As a special material, refractory is widely used in metallurgy, building materials, chemical industry and other high temperature processes. The performance and quality of refractory materials are clos

As a special material, refractory products are widely used in high temperature processes. However, different refractory products have their own advantages and disadvantages in terms of performance and

Silica is a common ore and has wide application value. According to the different composition and properties of silica, it can be divided into many types. This paper will introduce the classification

There are many kinds of refractories, usually divided into ordinary refractories (1580 ~ 1770 ° C), advanced refractories (1770 ~ 2000 ° C) and extra grade refractories (above 2000 ° C) ac
