We often use the experimental instruments in the laboratory: According to the specific needs to make all kinds of quartz instruments for laboratory: quartz square or round tube, quartz laser cavity, quartz three mouth tubes, quartz door, quartz releasing water bottles, quartz graduate, quartz flask, quartz spiral casing tube, quartz bottleneck, distillation quartz suit tubes, [...]
Quartz tube is a new type of quartz material. Its use is very extensive. At the same time quartz tube is very popular with its unique advantages in the plumbing industry. But the most important thing is that its cost performance is relatively high. Its price advantage, mainly reflected in the price and performance of [...]
Grinding is an important process in the manufacture of quartz rods. It has a direct impact on the quality of quartz rods of various parameters, as well as stability and service life, etc.. In addition to the specified dimensions of each process in the grinding and it is necessary to completely remove the damaged layer [...]
Quartz glass can be divided into three categories according to its optical properties: 1 Far Ultraviolet Optical Quartz Glass JGS1 Transparency in the UV and visible spectral range; No absorption bands in the 185-250nm band range; Strong absorption bands in the 2600-2800nm band range; Non luminous, light radiation. 2 Ultraviolet Optical Quartz Glass JGS2 Transparency [...]
About the uses of adding quartz in the porcelain, the main points are as follows: 1, Increase the body mechanical strength and transparency. 2, High temperature chemical affinity is very strong, compounds with many other oxide, high temperature liquid viscosity is very high, the increase of body binding capacity. 3, When firing out, due to [...]
1, Metallurgical industry: Mainly used in the manufacture of refractory brick, smelting silicon alloy (ferrosilicon, silicon manganese, chromium and silicon) and as flux. The pure quartz rod can be made of crystalline silicon. Crystalline silicon is the main raw material for the production of monocrystalline silicon, and silicon aluminum and silicon. 2, The construction industry: [...]
(1)Quartz can be used to make glass Flat glass, float glass, glass products (glass jar, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass equipment, conductive glass, glass cloth and anti ray special glass, etc. (2)Ceramics and refractories Embryo material and glaze of porcelain, high silica brick used in kiln, ordinary silica brick and [...]
The thermal expansion coefficient of quartz glass is only 1/10 to 1/20 of ordinary glass. The purity of quartz glass has an effect on the expansion coefficient. The linear expansion coefficient of the general transparent quartz glass （0-100℃） is 5.4×10-7. Opaque quartz glass is 5.5×10-7. High purity synthetic quartz glass is 4.9×10-7（0-200℃）-5.0×10-7（5-35℃）. Temperature(℃) 100 [...]
1.Electric fused transparent quartz glass It is by the electric resistance heating element in the vacuum pressure furnace melting ordinary crystal, through artificial or mechanical pull made of various quartz tubes.These products can be processed into a variety of instruments.This kind of glass is the most commonly used in quartz glass.It can meet the needs [...]
Fused quartz is made of high pure silicon by high temperature melting and condensation.Its main component is SiO2, and also contains Fe3+,Al3+,K+,Na+,Ca2+,Li+ and other trace elements.The fused silica has the characteristics of wear resistance, high temperature resistance and so on.Silicon is also a precious semiconductor material, so it is widely used in the fields of electronics, [...]
