General information on Pyrophyllite
Pyrophyllite is an alumino silicate mineral with a chemistry and properties similar to Talc. A main difference between Talc and Pyrophyllite is that magnesium is substituted for aluminium in the chemical structure. Pyrophyllite found early use in machinable ceramics [such as resistors, transducers, vacuum gaskets, insulators] due to it softness and ease of machining.
The main deposits of Pyrophyllite can be found in China and USA [Carolina’s ] - other sources can be found in Belgium, Brazil, Canada, Japan, Mexico,  Russia, Sweden, and Switzerland.
Industrial uses of Pyrophyllite inlude  tiles, refractories,  fillers, plastics, rubber, paint, insecticides and glass.

Barytes is a white crystalline solid and consists of Barium Sulphate. Uses include in medicine [as a 'Barium meal' and "enema" for radiation treatment], as a high temperature oxidizing agent, as a white pigment filler for paints, in the manufacture of linoleum, oil cloth and textiles, rubbers, paper and plastics manufacture. Barytes improved a paper's finish and provides slip in fillers. more Barytes

Diopside is a Calcium Magnesium Silicate. Colors differ markedly but often appear green due to the small presence of chrome. This feature is one of the reasons Diopside finds uses in gem stone Jewelry. Worldwide sources include mines in South Africa, Italy, Austria, Sri Lanka, Brazil, Canada and United States.more Diopside.

Pyrophyllite is a a soft ceramic material with a chemistry of hydrous alumino silicate and a structure, properties and uses similar to Talc. Benefits include chemical inertness, a high dielectric strength, a high melting point, and a low electrical conductivity. These unique properties make, Pyrophyllite useful for ceramic and refractory applications. more information on buying and selling chinese Pyrophyllite.

Titanium dioxide found in Australia, India, South Africa and the USA. Synthetic rutile can be produced from ilmenite. Rutile is used in paints as a paint pigment, as coatings for tiles, air treatment, fruit preservative, and in pollution improvements. Benefits include lightweight, high strength, non-corrosive metal and replacement of lead in paint. Industries include aerospace, automobiles, sports, and medicine.more Rutile.

Quartzite is composed of sandstone that has been metamorphosed and consists of > 90% silicon dioxide. This mineral is used as a raw material for the glass and ceramics industries and as flags, pavements, stones and tiles. Quartzite is often used in jewelry, due to its different colors in nature. Natural occurrences include Italy, Sweden and Norway. more Quartzite.
