性脆，有较高的抗压强度，对酸有较强的化学稳定性。价格便宜，属硬质填料，是摩擦材料中常用的增摩填料，因其硬度高，增摩效果显著，但其用量过大或粒径过上时，摩擦系数可高达0.6左右，只要用量、配比得当，并不明显产生噪音。
Feldspar powder
Crisp, high compressive strength, a strong chemicalstability to acid powder is cheap, is a hard packing, is increasing frictionfiller used in friction materials, because of its high hardness, frictionincrease significantly, but the amount is too big or too on the particle size,the friction coefficient can be as high as 0.6, as long as the amount, proportionof properly, not obvious noise.
