What are the Roles of Zirconia Refractory Raw Materials in Refractory Materials?
Zircon and ZrO2 refractories made of zirconia -based refractory materials have excellent chemical resistance and high-temperature performance. For example, zirconia bricks are used for the slag line of steel drums, ZrO2 bricks are used for the nozzle holes of sliding nozzles, and ZrO2 quality sizing nozzles for horizontal continuous casting. At the same time, the zirconia -based raw materials are introduced into other refractory materials, and the phase change of ZrO2 is used to greatly improve the performance of the original materials, especially the thermal shock stability. RS High-Quality Zirconia Bricks for Sale The Effect of adding Z irconia R efractory Materials Adding ZrO2 to refractory materials mainly has the following two functions. ①The main crystalline phase or the secondary crystalline phase is generated so that the material has special properties. For example, the most well-known fused corundum brick. The composition of the #33 fused cast zirconia corundum brick produce...
