Description of LITHIUM ALUMINATE
- Lithium aluminate (LiAlO 2), also called lithium aluminium oxide, is an inorganic chemical compound, an aluminate of lithium. In microelectronics, lithium aluminate is considered as a lattice matching substrate for gallium nitride. In nuclear technology, lithium aluminate is of interest as a solid tritium breeder material, for preparing tritium fuel for nuclear fusion.; Lithium aluminate is a layered double hydroxide (LDH) with a crystal structure resembling that of hydrotalcite.[dubious – discuss] Lithium aluminate solubility at high pH (12.5 – 13.5) is much lower than that of aluminium oxides. In the conditioning of low- and intermediate level radioactive waste (LILW), lithium nitrate is sometimes used as additive to cement to minimise aluminium corrosion at high pH and subsequent hydrogen production. Indeed, upon addition of lithium nitrate to cement, a passive layer of LiH(AlO 2) 2 · 5 H 2O is formed onto the surface of metallic aluminium waste immobilised in mortar. The lithium aluminate layer is insoluble in cement pore water and protects the underlying aluminium oxide covering the metallic aluminium from dissolution at high pH. It is also a pore filler. This hinders the aluminium oxidation by the protons of water and reduces the hydrogen evolution rate by a factor of 10.
Lithium aluminate also finds its use as an inert electrolyte support material in molten carbonate fuel cells, where the electrolyte may be a mixture of lithium carbonate, potassium carbonate, and sodium carbonate.

What is LITHIUM ALUMINATE?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is LITHIUM ALUMINATE which has developed particularly rapidly in recent years. Do you know about LITHIUM ALUMINATE?
- The official answer: Lithium alumina is an inorganic compound with the chemical formula LiAlO2, a colorless orthogonal crystalline crystal that does not decompose when used and stored according to specifications. Insoluble in water, it decomposes in case of acid. The substance may be harmful to the environment and special attention should be paid to water bodies.
What’s the application of LITHIUM ALUMINATE?
High temperature resistance, so that the diaphragm in the 180 °C oven placed for 1H can also maintain the integrity of the diaphragm;2. Alumina can neutralize the free HF in the electrolyte, improve the acid resistance of the battery, and reduce the gas inside the battery;3. Alumina has good wetting properties and strong liquid absorption and retention ability;4. Alumina maintains the closed pore of the diaphragm to avoid potential safety hazards caused by thermal runaway;5. Alumina can improve the mechanical strength of the base film itself and reduce the mechanical short circuit in the cycle process.
