Wholesale Manufactory supply 99% CAS 1310-65-2 Lithium Hydroxide White Powder

    Lithium hydroxide (LiOH) is a caustic alkali, Kb=0.66, pK=0.18, soluble in water is strongly alkaline, 1mol/L solution pH value of about 14, showing strong alkaline, white crystal powder or small particles, relative density of 1.46, melting point of 470℃, 942℃ decomposition. It is soluble in water, at 20℃, 100g water can dissolve 12.8g, due to the increase of solubility and solution density after dissolution, the concentration of saturated solution substances at 288K can reach 5.3mol/L, it is slightly soluble in ethanol, easy to absorb water and carbon dioxide in the air. Lithium hydroxide has a strong corrosive and irritating, should be sealed storage. Properties: white crystal or powder. Dissolves in water to form an alkaline solution. Formed by the reaction of 7LiCO3 or 7LiF with Ca(OH)2, purified by recrystallization and usually present as a monohydrate. Due to the low thermal neutron absorption cross section of 7Li (σ=0.0376), 7LiOH is used for PH regulation of primary water in PWR nuclear power plants. The 7Li content in 7LiOH for this purpose is required to be >99.9 (i.e., 6Li<0.1). Preparation: Lithium hydroxide is usually prepared by mixing lithium carbonate and lime milk into a slurry, heating with water vapor at 100 ° C, and filtering calcium carbonate. Lithium hydroxide monohydrate (LiOH·H2O) is obtained by absorbing water from lithium hydroxide in the air.

Application Area

1. 1.It is used in the preparation of positive electrode materials and electrolytes for lithium batteries. It is the key raw material for the preparation of power battery materials NCA, NCM (high nickel), and lithium iron phosphate. It is also used in the preparation of new negative electrode materials lithium titanate.
   2.Used in lithium-based grease additives, carbon dioxide absorbents, and important raw materials in petrochemical, nuclear, military, glass, printing and dyeing, biomedicine and other industries.
   3.Additives for environmentally friendly lithium-based greases.
