Different production processes and different combinations of raw materials will lead to changes in the physical and chemical properties of white fused alumina refractories. The strengthening of white fused alumina refractory materials is generally divided into two methods. One is to increase its performance by adding some special additives on the original basis; the other is to use composite material technology to combine white fused alumina with other substances. Get some new features and capabilities.
Introduction to the properties of white fused alumina refractories
The main characteristics of white fused alumina refractories are good heat resistance, strong corrosion resistance, high wear resistance, good mechanical strength and solvent resistance, etc. Specifically, white fused alumina performs well under high-temperature conditions, and its heat resistance reaches 2000°C, and it will not appear pulverization and cracks even in extreme high-temperature environments. In addition, white fused alumina has a smooth surface, is not easily attacked by external chemicals, and has a very strong resistance to acid and alkali corrosion.
Application introduction of white fused alumina refractory material
white fused alumina refractories are widely used in various high-temperature furnaces, heat treatment equipment, metallurgy, ceramics, chemicals, electric power, coal, glass, textiles and construction industries. For example, white fused alumina silicon carbide ceramics can replace traditional silicon carbide materials and be used in the manufacture of solar cells and other semiconductor materials; white fused alumina seals are used in high-tech fields such as aviation and aerospace, and can withstand high vapor pressure and high temperature of the solution. Corrosion; at the same time, white fused alumina refractories are also widely used in the manufacture of chemical equipment such as furnace charges, which can withstand high temperature and high pressure.
Summarize:
This paper introduces the material, performance, application, manufacture and characteristics of refractory white fused alumina in detail, and expounds the wide application prospect of this material in the field of high temperature sintering.
