Tabular Alumina Al2O3 99.2% min
Tabular Alumina: The plate-like crystal structure has small pores and many closed pores, and the porosity is roughly the same as that of fused corundum. It has high purity, good volume stability and minimal reheating shrinkage. The refractory or castable used for production has good thermal shock stability and bending strength after high-temperature treatment, but the price is higher than that of other alumina. High fire resistance; High corrosion resistance; High erosion resistance; High thermal shock stability; High strength and good toughness; Stable chemical properties. Tabular corundum is a kind of pure sintered corundum with complete shrinkage without adding any additives such as It has the characteristics of coarse crystal and good development crystal structure. The plate-like crystal structure has small pores and many closed pores, and the porosity is roughly the same as that of fused corundum. It has high purity, good volume stability and minimal reheating shrinkage.
Alumina (Aluminium Oxide) is the most widely used oxide ceramic material. Its applications are widespread, and include spark plugs, tap washers, abrasion resistant tiles, and cutting tools. Very large tonnages are also used in the manufacture of monolithic and brick refractories.

Features
1, sunscreen
The new type rolling shutter has different design in material and structure, which can effectively prevent glare and ultraviolet radiation. The utility model is suitable for various climatic and weather changes, and has long-term protective effect on indoor environment. The experiment proves that the shielding rate of the new type rolling window to sunlight is 100%
2. Heat preservation and energy saving
Our production of external sun shading rolling shutter Aluminum Alloy curtain sheet, middle filled polyurethane foam with high density, the authority of the State Department inspection certification, the heat transfer coefficient is only 5.3W/ (M2 - K) to realize the energy-saving insulation effect.
3, sound insulation, noise reduction
No noise type shutter window not only its own operation, and when Home Furnishing is located in the heart of the road and the airport noise zone, after installation can greatly reduce outside noise interference, living and learning are not affected.
4, security
The inner of the rolling window is provided with an anti pushing track and an anti prizing device, and the utility model can not be opened from the outside after being closed, and the utility model has the advantages of firmness, durability, safety and theft prevention.
High purity alumina powder is a compound, commonly known as aluminum oxide (Al2O3). It is odorless, white, crystalline powder. It has very high melting point. It is insoluble in water and difficult solubility in mineral acids and strong alkali. The variety formed at very high temperature is quite inert chemically. It is amphoteric in nature, and is used in various chemical, industrial and commercial applications.
High purity aluminum oxide
is the raw material for sapphire crystal. This type of pressed pellets are made from ultra high purity alumina. It is designed to provide high filling in crucibles used to make sapphire single crystals. The alumina materials RBST supplied are produced with latest eco-friendly and high technology. As a supplier for advanced materials, we continuously improving the service by cooperate with the manufacturers with high efficiency large volume production.
