Classification
Corundum block refractory material refers to the main crystal phase for alpha Al2O3 (corundum) refractory material. As it has high temperature resistance, high hardness,
high strength, oxidation resistance, corrosion resistance, good electrical insulation, air tightness and other excellent performances. Therefore, with the development of
modern science and technology, the application scope is larger and larger. Corundum is the name of the mineral, in 1798, the name is included in the mineralogy, Corundum
, formerly known as gems. The main chemical composition is Al2O3, which is a -Al2O3 crystal, which belongs to ionic crystal. Pure corundum crystal is colorless and
transparent, with a trace of chromium corundum crystal is pale red, commonly known as the ruby; containing trace Fe and Ti of corundum crystal is pale blue, commonly
known as sapphire. Production of corundum countries in the world are: Kazakhstan, South Africa, Canada and other countries
According to the crystal form, the corundum is divided into plate or tabular corundum, cylindrical corundum, granular corundum, single crystal corundum, microcrystalline
corundum. According to the appearance color is divided into white corundum, red corundum, blue corundum, purple corundum,etc.
Application
High hardness, good wear resistance, high strength, in the chemical system, used for various reaction vessels and pipelines, chemical pumps parts, mechanical parts, all
kinds of mold, such as wire drawing die, extrusion pencil core mould mouth; *, abrasives, bulletproof materials, human joints, sealing ring mill etc.
Corundum insulation materials, such as corundum light brick, corundum hollow sphere and fiber products, widely used in all kinds of high temperature furnace furnace wall
and furnace, high temperature resistant and insulation, high temperature resistance and heat insulation.
