JGS1 Fused Silica Research
Silica wafers originally developed to measure the quality of optical coatings. Translucent quartz tubes are often used to coat electrical elements and for a variety of other applications. Also in photovoltaic cells fused UV melt silicones are frequently used, such as those of the JGS1 series. [Sources: 1, 5]
Molten silica forms have excellent thermal and shock resistance and are inert to most elements and compounds, including virtually all acids, except hydrofluoric acid, which is highly reactive even at relatively low concentrations. The most common impurities are hydrogen peroxide and hydrochloric acid (Hydro - H2O), which can influence both the chemical properties of the wafers and their conductivity. Any element that is built into a larger piece will most likely contain bubbles, but applications should not be sensitive to inclusion. [Sources: 0, 4, 5]
Molten quartz is very strong under compression, so the design's compressive strength is well above 1.0, but its tensile strength must be at least as strong as that of a glass wafer, and perhaps even stronger. The tensile performance can be influenced by surface defects, which can greatly reduce the strength of the glass. [Sources: 0]
F Molten quartz can undergo large, rapid temperature changes without cracking, but this is accompanied by a large reduction in density, which leads to cracking and splintering. This limitation can be removed by high cooling with cristobalite, which causes the glass to fall back into a crystalline state under certain conditions. [Sources: 0]
You can send me a drawing or a findal of your product and I will make you an offer and agree with you, or you can send me a description of the material and its properties by e-mail. This material includes materials used in distant ultraviolet and infrared optical fields such as lenses. These lenses are used for UV photography because quartz glass has a much higher resolution than the lenses we produce for high resolution photography in the ultraviolet, infrared and near infrared fields. [Sources: 0, 5]
The birefringence tetragonal crystal structure leads to a difference in the refractive index and the reflection of quartz glass is generally 8. Spectral transmission is much better than with other types of glass and in the infrared range greater than with ordinary glass. In the visible range, the transitions in quartz glasses are also higher, but the ultraviolet range is larger and the infrared range is smaller. A spot that turns white is caused by the refraction of the light of the crystalline material and not by reflection. [Sources: 0, 2]
By adding a small amount of TiO2, the UV light is filtered out at 220 nm, which is called ozone-free quartz glass. Shortwave up to 340 Nm can be filtered out by adding a few micrometers of silicon dioxide (0.1% of the total amount) to quartz glass. [Sources: 2]
A thin article made of quartz glass, which is quenched by immersion in cold water for 1000 dollars to break, is available. Due to the additional risk of thermal fractures, a large number of silicon dioxide - molten quartz - used has been included in the list of the most dangerous materials in the world due to its high temperature, high pressure and high thermal conductivity, as well as the high cost of its use in electronics. [Sources: 0]
F quartz glass has a high thermal conductivity and a wide transparency range, which ranges from near-IR to UV. UV transparency is also used in the semiconductor industry: read-write-read is a kind of memory chip that stores data when the power supply is switched off, but can be deleted after heavy UV exposure. Silicon dioxide, with its wide transparency range, ranges from UV to near IR and has the potential to be used as a cost-effective, powerful and energy-saving storage material. [Sources: 1, 5]
JGS1 can be used in optics that operate in the deep UV and visible wavelength range, as well as in high resolution images. It can also be used in photovoltaics, as the optics work at wavelengths of only 10 micrometers and up to 1,000 nm. [Sources: 3, 4]
In the ultraviolet and visible ranges, JGS1 is transparent and has an absorption band in the wavelength interval of 170 - 250 nm. In the spectral range of 185-250, it has a wavelength range of only 10 micrometers and up to 1,000 nm and is translucent. It combines excellent physical properties with outstanding optical properties, such as high resolution images and low power consumption. J GS1 had or has absorption bands of 170-250 nm at wavelength intervals, but it is opaque and transparent in both the UV and visible ranges. [Sources: 1, 3, 4]
Absorption in the visible band is caused by the presence of transition metal ions and absorption at 2730 nm is an absorption peak of hydroxyl that can be used to calculate hydrate values. In the infrared range, it causes an absorption range of 1,000 - 2,500 nm and has intense OH absorption bands. Compared to JGS1 wafers, the transmission range of the more favorable JGS2 wafer was shifted to longer wavelengths. [Sources: 1, 2]
