An optical coating is the application of one (or several) metallic (or dielectric), films to an optical part’s surface. A coating applied to the optical part’s surface is used to increase or decrease the intensity of the reflection, beam, color, and polarization. The two most commonly used methods for coating optical parts are vacuum coating,…

What is Alumina Nanoparticle used for?
The coating material for the diaphragm of a lithium battery is High purity micro alumina. This ceramic coating acts as heat resistance and insulation to protect the power batteries from being short-circuited by high temperature or diaphragm melt. Additional ingredients for lithium battery cathode materials: Doped with lithium manganate and lithium cobalt, high-purity nanoalumina can…
