White corundum
White corundum is a high-quality refractory material with excellent heat resistance and chemical stability. It is made of high-purity alumina (Al2O3), sintered at high temperature and finely processed. With excellent performance and a wide range of application fields.Its characteristics are as follows:
1.High-temperature stability
2.Good corrosion resistance
3.High Strength and Hardness
4.Excellent insulation performance
5.Diversity in size and shape
Product Description
White corundum is a high-purity refractory raw material with excellent heat resistance and corrosion resistance.
White corundum particles: We provide various specifications of white corundum particles, and the size and shape can be customized according to customer needs. These granules have a highly pure alumina composition and are suitable for formulation and preparation of refractory materials.
White corundum powder: White corundum powder is a fine-grained white corundum material, which is widely used in the production of refractory coatings, refractory castables and refractory mortars. The fineness and uniformity of the powder can ensure the uniformity and stability of the product.
White corundum sand: White corundum sand is coarser white corundum particles, which can be used for lining and coating of high-temperature furnaces. It has good fire resistance and chemical stability, and can resist high temperature and corrosive gas.
Application
It can be used in the hearth lining of high-temperature furnaces and the top and bottom of high-temperature furnaces. Because white corundum has high hardness and compressive strength, it can withstand high temperature and mechanical stress, so it is used as a furnace top and bottom material.
It is widely used as a lining material for glass melting furnaces. Because of its excellent high temperature resistance and corrosion resistance, it can withstand extremely high temperature and chemical erosion during glass melting, and protect the furnace from thermal shock and corrosion.
White corundum powder can be used to prepare high-temperature refractory coatings, which can be applied to the surface protection of steel equipment. Coating white corundum refractory coating can enhance the heat resistance and chemical stability of the equipment and prolong the service life.
