What is the common name of aluminium/aluminum oxide crystals used in grinding?
Aluminium oxide Aluminium oxide Aluminium oxide (IUPAC name) or aluminum oxide (American English) is a chemical compound of aluminium and oxygen with the chemical formula . It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide. It is commonly called alumina (regardless of whether the element is spelled aluminum or aluminium), and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. It occurs naturally in its crystalline polymorphic phase α-AlO as the mineral corundum, varieties of which form the precious gemstones ruby and sapphire. AlO is significant in its use to
Aluminium oxide can be made in blanket, board, brick and loose fiber forms for various application requirements. Small pieces of aluminium oxide are often used as boiling chips in chemistry. It is also used to make spark plug insulators. Using a plasma spray process and mixed with titania, it is coated onto the braking surface of some bicycle rims to provide abrasion and wear resistance. Most ceramic eyes on fishing rods are circular rings made from aluminium oxide.
