Detecting free Iron :   Spray the surface with a solution of potassium ferricyanide. If free iron is present, a blue color will appear. This test is extremely sensitive and often gives false positive results, that is, it gives an indication of iron being present when it really is not. The ferroxyl solution must be made fresh each day by addition with Nitric acid. The ferroxyl tests are described in ASTM A380.

Lithium Hydroxide use in applications where greater reactivity and larger surface area. Use in the manufacture of lithium greases and other applications where exposure of personnel to Lithium Hydroxide Monohydrate needs to be minimized. Use in the manufacture of fine chemicals and specialty greases. A product with reduced levels of SiO2 is also available. Use in the manufacture of lithium greases, dyestuffs, specialty resins and other chemical specialties. Use as a pre-cursor in making critical battery materials like LiPF6 etc. Used in battery industry or producing other high-purity lithium compounds.
