Quartz is a form of silicon dioxide (SiO2). Its chemical structure contains one part silicon and two parts oxygen. It is the utmost abundantly found mineral in the Earth's surface.


It is a necessary component of igneous rocks granite and metamorphic rocks. A major mining area of quartz is Spruce Pine in North Carolina, United States.

Some the very infrequent and unique properties of quartz make it maximum sensible natural substances.

Essential Properties of Quartz:

Quartz is a crystalline, brittle and transparent strong material.
It is made of silica (SiO2) and other minor additives.
It has the capability to refract, reflect, and transmit gentle.
Quartz obtains its colour from electrically charged ions addition into it.
It has a steady framework of SiO4 tetrahedra.
Quartz crystals have piezoelectric properties.
Crystal oscillator is a universal piezoelectric use for quartz.
Quartz in its pure form, is colorless and transparent in nature.
Macro crystals varieties of quartz are transparent while Microcrystal types of Quartz are mostly opaque.

Different Method of Production of Quartz:

One Step production strategy:

This is the utmost universal single step strategy for quartz production. Firstly, the quartz sand is melted in a tungsten crucible. Here, it really is heated by the means of electrical heating parts. The fused material flows down from the crucible. Now the final shape is given. It will also be shaped into any form such as rods, tubes or plates.

This strategy of production is essential to obtain finished goods with very good mechanical strength and good thermal and optical properties.

H2/O2 flame fusion strategy:

The fusion strategy utilizes the H2/O2 flame. In this strategy, the raw material is heated up through a H2/O2 flame. The material is heated until it gets solely melted. In the final step a  lingot is obtained, which will also be shaped into any form such as plates, tubes, rods and disks.

The optical properties of quartz glass produced by this strategy is very good. In fact, this procedure is extremely a good idea to supply a finished good virtually free from bubbles or air gaps.

Electric vacuum fusion strategy:

The first production step is similar to Oxygen hydrogen flame fusion production strategy. It involves the quartz glass lingot formation.  Lingot is fused through an induction furnace to form products like tubes, rods and plates.

 All the crucibles produced by strategy are made of high purity. The Machining quartz through this strategy has a fantastic thermal stability. Other properties come with good coefficient of thermal expansion, low OH content and good transmission from the UV to the IR sort of wavelengths.

Electric cylinder fusion strategy

In this strategy, fusion procedure of silica sand occurs into a cylindrical mould. One electrical heater is positioned in the cylinder, while the others are positioned outdoor  . The rotation of the mould occurs around the axis all the way in which through the fusion of the quartz sand.  The melted quartz fixes on the inner wall of the cylinder. The larger diameter of quartz glass tubes are produced by this strategy.

Industrial Application of Quartz:

Quartz sand is used in the production of glass container, plates, and fiberglass.
It is a fantastic abrasive material.
It is used as foundry sand.
Refractory bricks are made of quartz sand.
It is used in the Petroleum Industry as Quartz sand has a high resistance to being crushed.
Quartz sand is used as filler in the paint industry.
Quartz makes a fantastic gemstone.

Quartz is one of the utmost sensible natural materials. Machining Quartz has been a good fortune as a result of its natural occurrence and abundance.  It is used in glass making industry  as a gemstone as a result of its luster, colour and diaphaneity. It is chemically inert and has very good heat resistance properties.
