Manufactured mica includes built-up mica, glass-bonded mica, ground mica, phosphate-bonded mica and reconstituted mica. Scrap mica is material that is below specifications for sheet mica because of substandard size, color or quality. Most scrap mica is used as the raw material for two types of ground mica: wet-ground and dry-ground.

The mica group of minerals are aluminosilicates with various metals. They split into fine sheets. Mica includes several closely related materials having perfect basal cleavage. All are monoclinic which means their crystals are shaped like one kind of prism.They tend towards pseudo-hexagonal crystals and are similar in chemical …

Mica classification. Chemically, micas can be given the general formula: X 2 Y 4-6 Z 8 O 20 (OH,F) 4 in which X is K, Na, or Ca or less commonly Ba, Rb, or Cs Y is Al, Mg or Fe or less commonly Mn, Cr, Ti, Li, etc Z is chiefly Si or Al but also may include Fe 3+ or Ti . Structurally the micas can be classed as di-octahedral (Y = 4) and tri-octahedral (Y = 6). …

Mica. Mica is a group of minerals. Mica is a sheet silicate and the sheets are easy to separate from each other because there are weak chemical bonds holding them together. This gives them perfect cleavage — the most characteristic feature of mica minerals. The term "mica" is, however, not easy to define. If we try to do it structurally ...

Mica is the name given to a group of silicate minerals that contain atoms of aluminum, oxygen, and silicon bonded into flat layers like the leaves of a book. They have perfect cleavage—that is, they split cleanly into thin flexible sheets. Members of the mica group may be colorless, black, brown, green, or violet, depending on their iron content.
