Product Details

Lanthanum Metal is a silver-gray active metal with a molecular formula of La. The powder is easily self-igniting in the air and easily soluble in acid, Insoluble in water, After exposure to oxygen in the air, it is very easy to exotherm into oxidized rare earth, The package is sealed and must not be in contact with air. It should be stored separately from oxidants, acids, halogens, and food chemicals. Avoid mixing. 

Application: As a raw materials for other Special alloys and hydrogen storage alloy additives, etc.
