What is Corundum?
Corundum, so-called ‘alumina’ and ‘Al2O3’, is a crystalline form of aluminium oxide. It also has two other names that are not widely known: Ruby and Sapphire. The name ‘corundum’ is derived from the word Kurundam, which is the Tamil-Dravidian word of ruby-sapphire. Due to its gem varieties, Corundum has super high hardness (9.0 on the Mohs scale, just next to diamond).
Johncera's Wear Resistant Ceramic Pipes For High Purity and High Abrasive Materials
Johncera is a professional advanced ceramic manufacturer, producing high purity alumina, zirconium toughened alumina, and zirconia. For conveying systems of high purity and high abrasive materials, advanced ceramics could construct a clean conveying environment, ensuring zero contact of conveying materials with metallic materials. Moreover, when conveying materials exhibit abrasive characteristics that will scour the system, advanced ceramics’ high hardness and wear resistance can avoid high purity conveying medium being polluted.
