The fused silica quartz rod for semiconductor and optical applications Diaries
Wiki Article
This leads to a fabric with Improved homogeneity and minimal OH-content for high thermal balance in the final software.
Fused silica glass, on the other hand, is produced by melting after which fast cooling silica, the primary ingredient of quartz. This method ends in a glass that is extremely transparent and proof against thermal shock.
Quartz rod is recognized for its high thermal and mechanical security, making it ideal for use in substantial-temperature applications.
For more demanding and significant-conclusion semiconductor applications Heraeus Covantics can offer multi-phase and improved solitary step electrically fused quartz rods in HSQ®300, HSQ®330 and HSQ®330S content high-quality depending on the purity specifications of The shoppers’ software.
Fused silica glass is usually Utilized in optical applications, which include lenses and mirrors, together with in the semiconductor and aerospace industries.
Mainly because of the massive Si-O chemical bond energy and limited framework, quartz glass has one of a kind Attributes, especially superb optical Homes of transparent quartz glass.
Fused quartz rods are available to satisfy the tight dimensional and Visible demands during the fabrication of batch furnace elements to create boats, wafer carriers and pedestals.
Discover our whole range of large-purity quartz rods with outer diameters from one.5mm to 40mm. Conventional length is 1240mm. Tailor made orders for longer lengths and additional diameters can be obtained.
Heraeus Covantics portfolio addresses various grades to address all OEM demands including tough ultra-substantial purity technical specs.
Acid and Alkali resistance: Except for hydrofluoric acid, quartz glass doesn't respond with any acid and base apart from hydrofluoric acid. The steadiness is 30 times of the ceramic, and a hundred and fifty periods of stainless-steel.
Heraeus Covantics manufactures artificial fused silica rods for main edge semiconductor applications. HSQ®900 and Spectrosil are classified as the corresponding substance qualities with components per billion course purity and zero bubble information.
Heraeus Covantics delivers fused quartz and silica rods in a number of materials grades and dimensions. The crucial facets of the fused quartz and silica rods are reduced bubble written content, superior purity and limited geometric tolerances.
Quartz rod, which is also known as quartz tubing, is often a style of fused quartz that is commonly Utilized in scientific and industrial applications. It's produced by heating and shaping fused quartz into a cylindrical condition, which could then be Reduce and machined into several sizes and designs.
*The above solution info is based on theoretical info and is particularly for reference only. Real technical specs may possibly fluctuate.
Their Outstanding large light transmittance (>ninety% in seen and UV spectra) will make them ideal for optical factors, fused silica quartz rod for semiconductor and optical applications making certain unobstructed mild transmission in optical equipment and imaging devices.
