锆英粉适用于盘片制造商
锆英粉是由天然矿砂—锆英砂粉碎而成。主要成分为ZrSiO4（硅酸锆）。理论上ZrO2为67.1%，SiO2为32.9%。现在市场上销售的产品以ZrO2含量计算纯度。 天然一级锆英粉中ZrO2含量为65%左右，比重4.6-4.7g/cm3，莫氏硬度7-8。
硅酸锆化学性质非常稳定，熔点2550℃。因此在摩擦材料中应用可以取得非常理想的效果。主要特点是：
1.提高摩擦系数。
2.由于其抗热震动特性，不产生震动噪音。
3.应用为增磨剂时磨损较小。
Zircon flour is made of matural ore-zirconium sand grinding.the main compostion is ZiSiO.ZrO is 67.1% and SiO is 32.9%.Now on the market by ZrO2 content product purity of calculation.Natural level zircon powder content for 65% of ZrO2,proportion of 4.6-4.7g/cm3,7-8’s hardness.
ZrSiO chomistry is very stable,melting point 2550℃.therefore in the friction materials can be obtained in the application of the ideal effect.Key features are:
***crease friction coefficient.
2.Due to its thermal vibration characteristics,no vibration noise.
3.When applied to increase grinding wear small.
