Recycled Nanoparticles Of Artificial Corundum As Fine

The most important characteristic of corundum is very high hardness number 9 on Mohr scale. That is the reason, why is mostly added to the cement mixture primary intended for high load flooring. In this paper were studied several type of recycled corundum classified due to its origin.


Possibility Of Using Recycled Raw Materials

Artificial corundum is divided into two kinds. White Corundum is produced by fusing of clean Al 2O 3 in electrical arc furnace. After crushed it and milled it on ball mills, arised corundum grains are several times magnetized and sieved according to the sizes. A block of Brown Corundum is smelted from calcinated bauxites, cokes and Fe cuts in
