What is Talc

The Talcum powder main ingredients are Talc.

Talc is generally white, slightly blue or green. The ingredients of Mg3 [Si4O10] (OH) 2 structure of the layered silicate minerals. Crystal belongs to triclinic system, leave the six-party single-crystal flake rare, massive dense, leaf-like, fibrous or radial aggregates.

Ground into powder with talcum powder called.

English name: Talcum powder or Talc powder

This product is for family-like magnesium silicate talc mineral salts, mainly composed of water-bearing magnesium silicate, by crushing after treatment with hydrochloric acid, washing, drying from.

Talc is the main component of water-bearing silicate talc magnesium.

Usually into a dense block, leaf-like, radial, fibrous aggregates. Colorless, transparent or white, but with a small amount of impurities and a light green, light yellow, Light brown or light red; cleavage was pearl gloss surface.

Hardness 1, the proportion of 2.7 to 2.8.

In the paper and used as a filler in rubber industry. Refractories for the metallurgical industry. Made use of talc-like ceramic with good dielectric and mechanical strength, is a high-frequency and ultra-high-frequency electric ceramic insulating material.

Hydrothermal alteration minerals are talc. Usually by the magnesium-rich rocks from hydrothermal alteration. Serpentinized peridotite intrusion in the late hot acidic aqueous solution and the role of CO2 can also be the formation of talc.
