White fused alumina is commonly prepared using several methods, with the ball milling method being one of the most prevalent. In the ball milling process, raw materials are mixed with milling media (such as glass or steel balls) and ground under high-speed rotation. Another method is the electric fusion process. In this method, raw materials are placed in an electric furnace, melted at high temperatures, and then cooled and crushed to produce white fused alumina.
