Zircon flour is made of natural ore-zirconium sand grinding. The main composition is ZiSiO2 content product purity of calculation. Natural level zircon powder content for 65% of ZrO2, proportion of 4.6-4.7g/cmâ¶, 7-8′s hardness.
ZrSiO chemistry is very stable, melting point 2550 degrees. Therefore in the friction materials can be obtained in the application of the ideal effect.
