Quartz

It is used for: special lenses and prisms and quartz-glass tubes for unlamps laboratory tubes and crucibles glass.

Mica

The platelet particle shape of Mica offers excellent flexural modulus properties, improved heat resistance, electrical properties and mechanical properties.

Talc

Talc, the softest of all minerals is known to everyone because of talcum powder. The softness, flakiness, and stability of talc makes it a desirable substance for many purpose.

Feldspar

In making the body composition of several types of procelain, china and earthenware and also in the preparation of glazes and enamel.

Calcite

Uses: In cements and mortars, production of lime, limestone is used in the steel industry.


Talc

mica

Talc, the softest of all minerals is known to everyone because of talcum powder. The softness, flakiness, and stability of talc makes it a desirable substance for many purpose. In industry it is mainly classified into hard and soft and fibrous and flaky. It is a platy mineral used for its reinforcing properties. Talc is commonly used as the functional filler for the plastics, and as an extender & pigments for paints. Finely ground talc is widely used in the polypropylene industry for its reinforcing properties.

In plastics it adds to the stiffness, dimensional stability, flexural modulus & resistance to creep. It also contributes to good flow, surface appearance and easier machinability of polymers. In plastics, the primary use area of talc is in Polypropylene (PP).
