YAG, is the abbreviation of yttrium aluminum garnet, the chemical formula is Y3Al5O12, is a composite oxide formed by the reaction of Y2O3 and Al2O3, belonging to the cubic crystal system, with garnet structure. The unit cell of garnet can be seen as a network of dodecahedron, octahedron and tetrahedral.
Storage method:
This product should be sealed and stored in a dry and cool environment, not suitable for long-term exposure to the air, to prevent agglomeration by moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidants, and be transported according to ordinary goods.
