Abrasive is to combine a boehmite, aluminum hydroxide and magnesium nitrate combined with the product

Abrasives grown in an aqueous gel abrasive abrasive technology has been considered a big step forward. Ministry of Industry abrasive early in the 1980s began using sol-gel processing method to generate an abrasive. Mineral technology manager explained, The abrasive is to combine a boehmite, aluminum hydroxide and magnesium nitrate  polycrystalline diamond  product. Magnesium nitrate is used as a modifier. These gel generated on the liquid taken out, allowed the formation of massive precipitate. then it is crushed into a desired size. And finally into the furnace calcination. This has been improved, like the very dense ceramic corundum abrasive as new. The sol-gel method of the production of  synthetic diamond  corundum normal  abrasive grinding  compared to the advantages of a gel abrasive after calcination in the broken, thus eliminating the micro-cracks. Abrasive micro-cracks on the grinding pressure, causing premature wear of the main factors abrasive.
