产品名称NAME：Zircon Powder（锆英石）
产品描述PRODUCTION DESCRIPTION：
Zircon is a friction raw material filler, with its Mohs hardness of 7.0 – 7.5, greatly increasing friction coefficient. Zircon is insoluble in water, dilute acids, and hot concentrated sulfuric acid. It is very slight solubility in hydrofluoric acid, reacts with hot concentrated alkali solutions, but does not react with cold dilute alkali solutions. Zircon with purity of 65%, as a friction raw material filler, will better increases the friction coefficient and reduces brake noise at the same time.
