(1) Chemical Vapor Deposition method (CVD)
The silicon tetrachloride liquid is brought into the burner by the gas bubbling method, then the high temperature flame is produced by the combustion of the hydrogen-oxygen gas to hydrolyze and melt the gaseous silicon tetrachloride. After the reaction, the silicon dioxide is deposited on the substrate on. CVD deposition device can be divided into two kinds, horizontal and vertical according to the structure. In contrast, the base rod applied vertical layout inside the vertical deposition device, generating a higher deposition rate, being able to prepare large-size quartz glass.
The reaction is as follows:
SiCl4 (gas) + 2H2 + O2 (gas) → SiO2 ↓ + 4HCl ↑
Quartz glass synthesized by CVD method has low metal impurity content, and its performance is better than that of fused silica glass, such as high deep ultraviolet transmittance, high optical uniformity and excellent radiation resistance, which can meet the needs of some high-tech fields. However, the quartz glass prepared by the CVD method has a serious drawback: since the preparation process is always in a hydrogen excess atmosphere, the content of hydroxyl groups in the prepared quartz glass is high. The researchers generally believe that the hydroxyl group led to that infrared absorption spectrum of quartz glass has a strong absorption peak at 2.73 μm, and the presence of hydroxyl groups can also lead to lower density of quartz glass, thereby reducing its mechanical properties and thermal properties.
(2) High-frequency plasma flame method
The most relevant part to the synthesis process is the plasma torch part in the whole deposition device. The torch is four-tube (shown in Fig. 3): the innermost quartz glass tube is used for conveying raw material gas, the second quartz glass tube is used for conveying oxygen, The third layer of quartz glass tube is used for conveying the working gas, the outermost layer adopts the oxygen-containing gas as the cooling gas, and the high-frequency coil surrounds the outermost quartz glass tube to excite the plasma; the raw material gas transported by the inner tube, after being mixed with the oxygen transported by the second layer, enters into the plasma area for reaction, and then generate quartz glass particles to be deposited on the base for completing the process of vitrification and obtaining high-quality hydrogen-free quartz glass ingot or quartz glass mound.

Quartz glass, Fused quartz, and  silica glass are synonyms for glass made from high purity quartz.  Quartz Glass is manufactured by melting naturally occurring high purity quartz sand at approximately 2000 °C, using either an electrically heated furnace (electrically fused) or a gas/oxygen-fueled furnace (flame fused). Fused quartz is normally transparent.
Quartz glass is a kind of special glass composed of a single component of silica. According to its purity, it can be divided into high-purity quartz glass, ordinary quartz glass and doped quartz glass, three categories. According to transparency, it is divided into transparent and opaque, two categories; because of a series of excellent characteristics such as high purity, excellent performance for light penetration, high temperature resistance capability, thermal shock resistance, stable chemical property and resistance to radiation as well as electrical insulation, it is known as the "king of glass"; it can be made of tubes, rods, plates, blocks and fibers, can be processed into various shapes of equipment containers, can also be cut, polished, polished into prisms, lenses and other optical components. Being mixed with a small amount of impurities can be made of new varieties of special properties such as ultra-low temperature expansion, fluorescent quartz glass, etc.; thus widely used in semiconductor, new light source, optical, instrumentation, thermal, metallurgical, chemical and building materials industry and laser technology, space technology, astronomy, nuclear engineering, optical communication and other high-tech fields.
A number of unique optical, mechanical and thermal properties have made quartz glass an indispensable material in the fabrication of high-tech products.

Purification Methods

Purification of silica for high technology applications uses isopiestic vapour distillation from concentrated volatile acids and is absorbed in high purity water. The impurities remain behind. Preliminary cleaning to remove surface contaminants uses dip etching in HF or a mixture of HCl, H2O2 and deionised water [Phelan & Powell Analyst 109 1299 1984].
