Product Overview

Description









Black corundum, also known as low aluminum corundum, is in the electric arc furnace, the bauxite melting and produced a kind α-Al2O3 and iron spinel as the main mineral phase of the gray-black crystals, which is characterized by the low content of
Al2O3,and a certain amount of Fe2O3 (10% or so) exists, and thus has a moderate hardness, high toughness, high temperature resistance,thermal stability of the performance of the characteristics of the state. It is mostly used for free grinding, such as polishing and rough grinding before plating of products, mainly used for polishing and sandblasting of stainless steel, metal products,optical glass, bamboo and wood products, and it is a novel abrasive for manufacturing resin grinding wheels, cutting discs, and abrasive cloth.




Name
Black corundum
Commonly used specification
Particle size of sand:3-5mm F:16,20,24,30,36,46,60,80,100,120,150,180,200,320
proportion of appearance
3.5g/cm3 Black granular.
raw materials
The bauxite in electric arc furnace smelting and become a kind of is given priority to with alpha AL2O3 and spinel mineral phase-colored crystals.
production process
Raw material sorting-electrolytic refining - crushing - in addition to the iron magnetic separation-screening-physical and chemical inspection-finished product packaging-warehousing
performance feature
Basic particle concentration, low linear expansion coefficient, good toughness, high grinding ratio.
Use
Stainless steel, metal, glass, wood products sand blasting, polishing, grinding wheel, cutting slices, sandpaper.
indicators
AL2O3 content is 85%, SiO2 content 5-8%, Fe2O3 content of 6-9%, content of TiO2 2-4%, true density of 3.5 g/cm after, the highest melting point temperature 1850 , 2050 1600 when the linear expansion coefficient of 7-9.










1. Metal and glass polishing.
Black corundum is used for polishing and sandblasting of stainless steel, metal products, optical glass, bamboo and wood products, etc. It can improve the finish of the processed parts, and is suitable for the bottom polishing of parts before plating, as well as the polishing of aluminum products.
2. Wear-resistant material.
Because of its high hardness and wear resistance, black corundum can be used for laying wear-resistant and anti-skid road surface,bridge deck, parking lot,etc. It is especially suitable for areas requiring high wear resistance such as sharp curves and
stee slopes.
3. Resin abrasives.
Black corundum can be used to make abrasives such as resin grinding wheels, resin cutting blades, resin abrasive discs, ultra-thin discs, etc. These abrasives are used in industry for grinding and polishing of metals, wood and other materials.
4.Coated abrasives.
Black corundum is compounded with brown corundum or calcined brown corundum to make coated abrasives, which are suitable for polishing wood, metal, etc.
5. Fiber polishing wheel.
Black corundum is used to make fiber polishing wheels, suitable for grinding and polishing of various workpieces.
6. Conductive material.
Specially treated black corundum has excellent electrical conductivity and can be used to make high-performance conductive materials.






25kg or 50kg per bag,or special pakcing requirement is acceptable.
