What are the advantages of talc?

Talc has excellent physical and chemical properties such as lubricity, anti-adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, softness, good gloss, strong adsorption, etc. The crystal structure is layered, so it has a tendency to split into scales and a special smoothness. If the content of Fe2O3 is high, its insulation is reduced.

The talc is soft and has a Mohs hardness coefficient of 1 to 1.5. It has a slippery feel. The {001} cleavage is extremely complete, and it is easily split into thin slices. The natural rest angle is small (35° to 40°), which is extremely unstable. The magnesite, magnesite, lean or dolomitic marble of silicified and shale petrochemical, except for a few moderately stable, generally unstable, joints, fractures, physical and mechanical properties of ore and surrounding rock on the mining process The impact is great.
