Product Introduction:
Zirconium corundum based on aluminum, zirconium material is given priority to, after 2250 ℃ high temperature smelting, to mark the special processing technology and through forming. According to the content of ZrO2, generally have low zirconium corundum (ZrO2 10-15%), zirconium corundum (ZrO2 25%) and high in zircon corundum (ZrO2 40%).
Zirconium corundum main crystal phase for alpha Al2O3, phase for the baddeleyite, there is a small amount of glass phase. Zirconium corundum and tough, compact structure, high strength, good thermal shock resistance, generally in taupe. In order to ensure the quality of zircon corundum, except for the reasonable selection of smelting parameters and process, cooling process and processing technology, choose the appropriate additive, reduce the SIO2 content in zircon corundum, make of Al2O3 and ZrO2 eutectic and uniform structure, etc. Also is the key of zircon corundum production.
