Hydrotalcite Mg 4 .3Al 2 (OH) 12 .6CO 3 - mH 2 O
DHT-4A is a synthetic hydrotalcite compound that has recently been further used in the field of plastics processing, such as a stabilizer for the production of polyolefins (halogen scavengers).
The natural hydrotalcite {Mg 6 A l2 (OH) 16 CO 3 - 4H 2 O} has a small amount of sediment in the Urals of Russia and the Snarum of Norway. In 1966, Japan Concord Chemical Industry Co., Ltd. successfully synthesized hydrotalcite for the first time in the world. The first discovered the use of hydrotalcite as an antacid in the pharmaceutical industry. This product has been sold worldwide through some famous pharmaceutical factories.
The chemical composition is Mg 3 [Si 4 O 10 ](OH) 2 , and the crystal belongs to the triclinic layered structure silicate mineral. Pseudo-hexagonal sheet-like single crystals are rare, generally in the form of dense blocks, leaves, fibers or radial aggregates. White or various light colors, the streaks are often white, fat luster (blocky) or pearl luster (sheet aggregate), translucent. Mohs hardness 1, specific gravity 2.6-2.8. One set is extremely cleavable and the sheet is flexible. It has a slippery feel, strong insulation and strong insulation.
Identification features: According to the light color, low hardness (nail can be scored), with a sense of slippery, a set of extremely complete cleavage and other characteristics, can be distinguished from similar minerals such as pyrophyllite and massive serpentine.
Talc is a hydrothermal alteration mineral. Magnesium- rich minerals often turn into talc after hydrothermal alteration, so talc is often an illusion of minerals such as olivine, pyroxene, hornblende, and tremolite . Talc is widely used in paper, ceramics, rubber, paint, refractory equipment, textiles, dyes, foundry and pharmaceutical industries. The blocky talc is soft, smooth and soft, and is used to engrave handicraft materials.
