Synthetic Corundum: high hardness and transparence
Synthetic corundum is an industrial product. It is melted of high qualitiy aluminium oxide. Synthetic corundum consists of about 99 % aluminium oxide. The outstanding property of synthetic corundum is a high hardness. Only diamonds are tougher. This high hardness is a challenge for every grinding technology. Our micronized synthetic corundum SEPASIL is characterized by a narrow grain size distribution. Another refining step is the surface-treatment with silans or silan-based substances which can be adjusted to the respective application.
