Aluminum oxide powder

This product is prepared by the ammonium aluminum sulfate method and features high purity, uniform particle size, low water absorption, stable chemical properties, and excellent crystal orientation, ensuring excellent sintering stability when producing corundum‑type gemstones. 5N gemstone powder: With a purity of 99.999% and extremely low impurity levels, it serves as a raw material for manufacturing 5N gemstones. White gemstone powder: By adding appropriate amounts of other elements, the toughness of the sintered corundum can be enhanced without causing discoloration, making it suitable for producing white gemstones. 5# ruby powder: Adding Cr₂O₃ imparts a red color to the gemstone; this powder can be used directly for sintering 5# rubies, achieving a color that meets market demands.
