What is Pyrolytic alumina? Pyrolytic aluminais a white crystalline powder. Easy to absorb moisture but not deliquescent. Melting point 2050℃; Boiling point 2980℃; The relative density is 3. 965. High hardness, Mohs hardness of 8.8. The volume resistivity of the electrical insulator is (1.2×1013Q．cm) at 300℃. Almost insoluble in water and nonpolar organic solvents such as ethanol and ether. Very little solubility in weak acid or weak base. Dissolved in concentrated sulfuric acid, slowly dissolved in an alkaline solution to form hydroxide.
Preparation of Pyrolytic alumina powder Aluminum hydroxide is heated and dehydrated to prepare aluminum oxide. Or react aluminum chloride vapor with oxygen or water vapor at above 1000℃ to obtain particulate alumina. Alumina can also be obtained by direct thermal decomposition of salts such as aluminum sulfate and aluminum nitrate at 1200 ~ 1300℃. Uses of Pyrolytic alumina powder Pyrolytic alumina is mainly used as an analytical reagent, dehydration of organic solvent, abrasive and polishing agent, and also used as a grinding mixture for cracking yeast cells or microbial groups. It is used in lithium battery diaphragm material to improve high-temperature resistance and safety; it can also be used in lithium battery anode to improve conductivity and reversible discharge capacitance; used in negative electrode coating to improve temperature resistance and safety. It is used in powder coatings and photocopier inks to improve their charge rate and fluidity. It is used in various types of high-temperature resistant thermal insulation panels. Electret masterbatch of melt-blown material to improve charge adsorption capacity. The phosphor coating applied to the lighting industry can make the luminescence uniform, reduce the light attenuation and reduce the harm of ultraviolet light. Its ultra-fine characteristics can be used to improve the gloss and printability of paper. Price of Pyrolytic alumina powder Pyrolytic alumina powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Pyrolytic alumina powder. A large amount of large amount will be lower. The price of Pyrolytic alumina powder can be found on our company's official website.
