Stability
1. If used and stored in accordance with the specifications, it will not decompose, and there are no known dangerous reactions. Avoid oxides.
2. When aluminum oxide fiber is used to reinforce metal, it has good solubility with metal. In addition, it does not cause a chemical reaction to metals, making it an ideal metal-reinforced fiber. Alumina fiber is an important variety of polycrystalline refractory fiber. The thermal conductivity, heat shrinkage rate and heat capacity of alumina fiber are low. It has the characteristics of high temperature resistance and high heat resistance. The long-term use temperature is 1300~1400°C, which is higher than ordinary aluminum silicate fiber (1000~1100°C), and its maximum use temperature is 1500~1700°C. Compared with non-oxide fibers such as carbon fiber and silicon carbide fiber, alumina fiber not only has excellent properties such as high strength, high modulus, and high temperature resistance, but also has good high temperature oxidation resistance, corrosion resistance and electrical insulation. . It can be used in acidic environment, oxidizing atmosphere, reducing atmosphere and vacuum condition. It also has certain corrosion resistance to alkaline environment, but it is easily corroded by lead vapor and vanadium pentoxide.
3. Easy to absorb water but not deliquescence. It is an amphoteric compound.
4. It can cause breathing difficulties. It is best to operate in a fume hood and store under dry and inert conditions.

Function
1. Used for polishing abrasives, artificial teeth, artificial bones, magnetic tapes, picture tubes, red sapphires, high-density ceramic substrates for electrical use, etc.
2. Used to manufacture artificial gems, main parts of YAG laser crystals and integrated circuit substrates. Used as analytical reagent and high-grade ceramic raw material for arc tube of high pressure sodium lamp.
3. Industrial high-temperature furnaces such as heating furnaces and soaking furnaces for forging. Can be used as sealing material and filling material. It can also be used as reinforcing fiber for reinforcement, lining of kiln, calcining furnace of electronic components (IC board, ferrite), etc.
4. Used as catalyst and catalyst carrier, it is the main catalyst and carrier in petroleum refining and petrochemical industry. It is also used as a dehumidifier for air and other gases, as a deacidifier for transformer oil and turbine oil.
5. Used for rare earth three primary color phosphors, long afterglow phosphor raw materials, sub-micron/nano-level abrasive materials, etc.
6. Used in functional ceramics, electronic ceramics, laser materials, adsorbents, chromatography, etc.
7. Used as analytical reagent and catalyst
8. It can be used as abrasive material and refractory material
9. Used as desiccant, adsorbent, catalyst carrier
10. Used as aluminum silicate fiber binder, catalyst carrier, textile auxiliaries, etc.
