White corundum is a kind of fused alumina products made from high quality alumina powder. White corundum is characterized of high hardness, high purity, excellent selfsharpening, big grinding power, less heat, high efficiency, acid corrosion, high temperature resistance, good thermal stability.
A coated abrasive article comprising a backing and fused to the backing on aluminum is attached with an adhesive zirconia abrasive grains. These fused alumina zirconia abrasive grain comprising: ZrO2 + HfO2 between about 35wt% and about %, and between about % and about 65wt% of Al2O3, SiO2 of less than about % and other oxides of less than about 10wt%.
Alumina abrasive white fused alumina grits for sandblasting. White corundum(WA) is manufactured from Aluminia powder by crystal electrofusion process at high termperature of over hardness is a little higher and toughness is a little lower than brown has the advantages of high purity, good sharpness, strong grinding force ...
Wollastonite is a naturally occurring calcium silicate that is formed from quartz and calcium carbonate at a temperature of about 450°C. The structure of the individual wollastonite particles is determined by the respective geological formation and by the processing technology selected.
White Fused Alumina Micro Grits are produced by the grinding classification of selected Macro grain feed stock in an advanced milling and classifying facility. This ensures an iron free product of narrow particle size distribution and high whiteness.
Prominent feature is the small crystal size impact resistance, due to a selfprocessing mill crushed particles are mostly spherical particles, dry surface cleaning, easy binding agent combination. Year the company provides silicon carbide, white fused alumina, corundum powder, green silicon carbide powder and sand grain size.
Calcined and Fused Alumina. Calcined alumina powders are typically used for metal lapping and polishing, as well as have been the traditional rough and final polishing abrasive for many years and is relatively inexpensive and readily available. Calcined alumina grains consist of single platey crystals, whereas fused alumina is more blocky in shape.
White and brown Fused Alumina are extensively used in precision blasting where iron free and silica free operations are required. These grains are also used for shot blasting purpose, as polishing media and refractory grade WFA is used as raw material for high alumina refractories.

Both fillers can be used to extend rigid and flexible thermoplastics, and reinforced and unreinforced thermosets. They are relatively soft ( to Mohs scale), which results in reduced equipment wear, and are very white in color (averaging 98 on the Beckman scale). Also produces a calcium sulfate microfiber called Franklin Fiber filler.
