Fluorite ( Calcium Fluoride )

Fluorite ( Calcium Fluoride )

Fluorite (also called fluorspar) is a mineral composed of calcium fluoride, CaF2। Calcium Fluoride is a water insoluble Calcium source for use in oxygen-sensitive applications, such as metal production. In extremely low concentrations (ppm), fluoride compounds are used in health applications. Fluoride compounds also have significant uses in synthetic organic chemistry. They are commonly also used to alloy metal and for optical deposition. Certain fluoride compounds can be produced at nanoscale and in ultra high purity forms. Calcium Fluoride is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality Nanotechnology Information and Quantum Dots elemental powders and suspensions, as alternative high surface area forms.

Limestone

LIMESTONE ( CALCIUM CARBONATES )

The very pure limestone located in Sammalut formation Elminea governorate 200 km south Cairo, this formation has the high purity due to the microfossiles which lived in the past on the marine environment ( biological depositions )। Whiteness degree not less than 90% and the chemical purity of Ca CO3 99।9% min.

Quartz

Quartz

Quartz is the rock known under the name of el Marw। It is named after the metal that makes it to signify its blocking nature। The bigger part of it is used in the production of iron ingots (ferrosilicon ingot). The ground material is used in the making of ceramics, but as for the transparent quartz, it is used for electronic purposes and radar as well as optics since certain types of it produce lenses, slices and light prisms.

Talc

It mainly contains hydrated magnesium silicates and is found in the shape of lenses or veins inside the rocky base, especially the base and upper-base veins। The dimensions of raw bodies amount to 80 m. high and 50 m. wide and range from 20 m. to 5 m. in thickness. The reserve of it is estimated to be 365 thousand tons.

Feldspar

Feldspar

Feldspar is used in various industries, but it is mainly used in thermal industries such as in the making of pottery, porcelain, faience, glass and metal painting through functioning enamel। A little amount of it, not more than 10 %, is used for other purposes like the filling materials, painting and for the making of some sorts of soap.
