主要成分是硫酸鋇，化學性質非常穩定，不溶于水，也不溶于**和硫酸。硫酸鋇是摩擦材料中普遍應用的一種摩擦性能調節劑.它能使摩擦系數穩定，摩耗小，特別是在高溫下能形成摩擦界層，能防止對偶表面擦傷，使對偶表面磨的更光潔。

 maincomponents of barite is barium sulfate, chemical properties are very stable,insoluble in water, not soluble in hydrochloric acid and sulfuric acid.Bariumsulfate is a kind of friction performance regulator is widely used in frictionmaterials. It can make the stable friction coefficient, wear small, especiallythe friction boundary layer can be formed at high temperature, can preventgalling dual surface, thus dual surface grinding smooth.
