What about talc?In fact, I would like to know whether asbestos and talc are crystals and, if so, what types of crystals do they belong to?
Talc is hydrothermal alteration minerals. Magnesium rich minerals by hydrothermal alteration often becomes the talc talc, usually with olivine, enstatite, hornblende, tremolite minerals such as talc. The illusion is a kind of common silicate minerals, it is very soft and has a creamy feel. It has been elected 10 to represent the 10 mineral hardness level, known as the Moss hardness, at the 10 levels, the first (a is the most soft) is talc. Soft talc can replace the chalk to draw traces of white talc in bulk, general. Leaf shape, fibrous or radial, color is white, gray, and will contain other impurities with various colors. Many uses such as talc, refractory material, papermaking, rubber packing, pesticide absorbent, leather coatings, cosmetic material and sculpture materials etc.Functions and indications] diuresis, heat, dampness and astringing sores. For hot stone, shower, urine hot astringent pain, damp heat polydipsia, watery diarrhea; external treatment of eczema, eczema, prickly heat. For urination, shower drain astringent pain, with Cheqianzi, etc. for Akebia products; caused by damp heat with watery diarrhea, tuckahoe, coix seed, plantain seed is used to heat. Symptoms can be matched with connate licorice, fresh rugosa, fresh Perrin used the same treatment; wet chest tightness, short red urine, with coix seed, rice leaves connate, equivalent. In addition, this product can receive external heat with wet. Treatment of eczema, prickly heat, but with gypsum, alum calamine furnace, is used.
Asbestos was used early in weavingMany kinds of asbestos, depending on its mineral composition and chemical composition, can be divided into chrysotile and amphibole asbestos. Two kinds of chrysotile asbestos and asbestos production, it is one of the most, with good spinnability. Amphibole asbestos can be divided into blue, tremolite asbestos, asbestos actinolite asbestos, chrysotile production than less.
Asbestos is also called "asbestos" for commercial terms, which has high tensile strength, high flexibility, chemical and thermal erosion resistance, electrical insulation and with silicate mineral products spinnability. It is a combination of natural fibrous silicate minerals. Under the jurisdiction of the 2 class a total of 6 kinds of minerals (a serpentine asbestos, amphibole asbestos, asbestos, actinolite anthophyllite tremolite asbestos asbestos, iron, etc.). By asbestos fiber bundles, and fiber bundles by a long and thin can separate fiber asbestos. With high flame resistance, electrical insulation and thermal insulation, fire prevention is important insulation and insulation materials.Asbestos was used early in weaving
