A process for producing FUSED zirconia Alumina Abrasive grains composition close to the Eutectic

摘要

Preparation method of Abrasive grains of alumina - zirconia by Melting and Cooling rapido.el contains Abrasive alumina - zirconia composition close to the Eutectic (35 - 50 zirconia) and prepares melting in Electric Furnace, alumina, zirconia and Yttrium oxide Y2O3,,. This last n weight between 0.1 and 2.During the pouring into Molds, Fusion is performed under reducing conditions slightly for what can an / added immediately before Discharge, carbon, Aluminum and zirconium metal. The Cooling should be fast to get a Middle spacing Rods of 4000 angstrons Zirconium in the centres of the Eutectic cells.After Cooling, the product is Crushed and sieved, separating the different Taman / os which are used to apply on flexible Substrates.
