Ceriumhydroxidemin - Use

Open Data Verified Data

used as an additive in the glass industry, as a plate glass grinding material, has been expanded to glasses glass, optical lens, the grinding of the picture tube, from decolorization, clarification, the absorption of ultraviolet rays and electron rays of glass. It is also used as an antireflection agent for lens of glasses, and cerium is made into cerium titanium yellow to make the glass light yellow. Used in ceramic glaze and electronic industry, as a piezoelectric ceramic penetration agent. Also used in the manufacture of highly active catalysts, gas lamp incandescent cover, X-ray with fluorescent screen.

Ceriumhydroxidemin - Safety

Open Data Verified Data

packed in an iron drum lined with a two-layer polyethylene plastic bag with a net weight of 10kg or 40kg per drum. Should be stored in a ventilated, dry place. Packaging breakage should be prevented during storage and transportation. Toxicity and protection of rare earth salts can reduce the content of prothrombin, so that its inactivation, and inhibit the formation of thromboxane, fibrinogen precipitation, catalytic decomposition of phosphoric acid compounds. The toxicity of rare earth elements decreases with the increase of atomic weight. Inhalation of dust containing cerium, occupational pneumoconiosis, its chloride has damage to the skin, can stimulate the mucous membrane of the eyes. Maximum allowable concentration: cerium oxide 5mg/m3, Cerium hydroxide 5mg/m3. Work should wear a gas mask, such as radioactive to carry out special protection, the dust should be prevented from scattering.
