Division standards of all kinds of mineral hardness in Mill machinery: Hardness: Because this test is destructive to materials, it can only be made on the original stones or not precious ores. Hardness can be divided in to two kinds, one is absolute hardness, and the other is Mohs scale of mineral hardness (a relative […]

Potash feldspar, also known as orthoclase, belongs to monoclinic system. It is usually flesh red, white or gray. Density 2.54-2.57g/cm, specific gravity 2.56-2.59g/cm3, hardness 6. It has the characteristics of low melting point (1150 ± 20 ℃), long melting interval and high melting viscosity. It is widely used in industrial sectors such as ceramic blank, […]
