Main use of Yttrium(III) oxide

Submitted by admin on Mon, 10/22/2018 - 09:01

Yttrium (III) oxide, also known as yttrium oxide, has a chemical formula of Y2O3 and a molecular weight of 225.81.

Yttrium(III) oxide is a yellowish crystalline powder with white color, insoluble in water and alkali, soluble in acid and alcohol. When exposed to air, it easily absorbs carbon dioxide and water and deteriorates. Used as a white hot gas lampshade, color TV phosphor, magnetic material additive, and also used in the atomic energy industry.

Sunscreen mechanism of zinc oxide

Submitted by admin on Fri, 10/19/2018 - 08:14

Zinc oxide is an important and widely used physical sunscreen. The principle of UV shielding is absorption and scattering. Zinc oxide belongs to the N-type semiconductor, and the electrons on the valence band can accept the energy transition in the ultraviolet light, which is also the principle that they absorb ultraviolet light. The function of scattering ultraviolet rays is related to the particle size of the material.
