White corundum is widely used in the market, and white corundum manufacturers produce electric fused white corundum products with advantages in response to the requirements of various industrial produ

White corundum is generally used for refractory materials or abrasive use, and the figure of white corundum can be seen in many scenes. When using corundum products of different particle sizes, there

1. Brown corundum has the characteristics of high purity, good crystal formation, good self-sharpness, strong fluidity, low expansion coefficient, corrosion resistance, high temperature resistance and

Brown corundum is also known as emery, the main chemical composition of brown corundum is AL2O3, its content is 95.00%-97.00%, the particle shape is uniform, into angular crystal, with sharp edges, hi

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
