Pink Alumina Oxide is fused from high-purity alumina powder,
chromium and other materials in an electric arc furnace at very
high temperatures. The inclusion of chromium gives Pink Alumina
Oxide not only its characteristic pink or ruby colour, but also
even greater hardness and toughness than White Alumina Oxide. Pink
Alumina Oxide has sharp edges and extraordinary durability, and is
available in sizes ranging from large grains to micro-powders.
According to the content of Cr2O3, Pink Alumina Oxide have three
kinds: Low Chromium, Medium Chromium, High Chromium.
