BLACK SILICON CARBIDE P280 D50:52.2±2.0UM
Black silicon carbide is also called black carborundum ,black SiC,which is produced in electrical internal resistance furnaces from high purity silica sands and petroleum coke.
Zhengzhou haixu abrasives co.,ltd,founded in 1999,has been producing and exporting black silicon carbide and green silicon carbide for more than 20years.
For micropowder manufacturing,we take water and acid washed and overflowing classification which make it more clean and size more concentration.
For the sizes of black silicon carbide,we mainly produce the following sizes:
