What is the different between platelet calcined alumina and white fused alumina

Platelet Calcined Alumina is a specialized form of alumina (aluminum oxide) that is used in various high-tech applications, including the semiconductor industry. When it comes to Gallium Arsenide (GaAs) wafers, platelet calcined alumina can be used in several critical processes:

Polishing and Planarization:

GaAs wafers require extremely smooth and flat surfaces for the fabrication of semiconductor devices. Platelet calcined alumina is often used as an abrasive material in polishing slurries to achieve the desired surface finish. The platelet morphology of the alumina particles helps in achieving a uniform and controlled material removal rate, which is crucial for high-precision applications.
