Silica is the most popular mineral which we can get in large quantity on the outside of the earth. Most of the minerals found on rocks include silica as its main component. There are many sources where silica can be gift i.e. On huge hills, quartz crystals, sandstone, quartz sand also known as silica sand, quartzite, Tripoli, flint, opal, diatomite etc. Also you can find them in chalcedonic forms such as onyx and agate and so on. Nearnessy of silica varies with the colour i.e. They are found in yellow topaz also known as false topaz, purple quartz, milky quartz which is also known as rose quartz and also in smoky quartz. In the introductory stages of building pottery and silicate glasses, silica is used. The two forms in which silica can be obtained are crystalline forms and also in amorphous form also known as vitreous silica. They can also be found on silicon compounds or silicon's outside in the non crystal form.
Crystalline silica can be classified in three separate forms namely, tridymite, quartz and cristobalite and these crystalline forms comes in two separate forms i.e. Low and high. Fused silica is the only pure silica with nearby 99.4 - 99.9% of silica gift in it. This fused silica is in general used in industries dealing with electronics and they are made by plasma arc, carbon electrode fusion or gas fired continual extrusion and carbon arc. Because of its high insulating and dielectric properties, roughly 70% of the electronics industries use fused silica in its experiments. Some of them also use fused silica in investment casting or as a refractory material as when kept at high temperatures it has a capability to gain back its strength.
The main properties of silica are:
Battle Of Tripoli
1. It is a good electrical insulator.
2. Thermal stability of silica is very high.
3. Has a high resistance to abrasion.
Production of silicon:
Most of silicon is used in the yield of steel by development them as silicon manganese or ferrosilicon. By mixing the gaseous compound of hydrogen and hydrogen chloride and powdered crude metal, we can make semiconductor silicon.
Electronics industries mostly use silica in its working. The main areas in electronics industries where silica is used are:
1. Circuit boards: Because of insulating and dielectric properties, fused silica is most widely used in electronic circuits.
2. Semiconductors: Its internal electronic buildings makes it a good semiconductor and that is the presuppose why they are used in applications related to integrated circuits.
3. Refractory Materials: it has a capability to speak its drive even at high temperatures and because of this property they are used as a good refractory material. This is in general because silica has very high melting point, has very high abrasion resistance and low thermal expansion.
4. Production of glasses: silica is the traditional material used in the yield of silicate glasses. They are either mixed with soda and lime which produces normal glasses which are used in windows, jars, bottles, plate glass and light bulbs. Also we can make shock defiant glasses when silica is mixed with soda and boron oxide.
