White Fused Alumina Oxide

White Fused Alumina
White Fused Alumina Oxide is produced from high-quality industrial alumina powder through high-temperature smelting and crystallization. With an Alumina purity exceeding 99%, it presents a pure white color and extremely low impurity content. Boasting a Mohs hardness of 9.0, it provides exceptional cutting force and stability during grinding processes. Its chemical stability ensures performance in harsh environments involving high temperatures, acids, or alkalis.
