powder made of transparent quartz glass (ground fused quartz)
Powders made of transparent high-quality quartz glass are white powder with a mass fraction of SiO2 – 99.97 – 99.99% and a fraction size of 5 microns or more. The powder production technology ensures high chemical purity of the product.
Main characteristics of powders
Content of crystalline phases, % Coefficient of thermal expansion -1/degree K High chemical purity % Material density kg/m3
0 (3.5×10-7) SiO2-(99.97-99.99) 2.21×103
Powders are characterized by high chemical resistance to alkaline and acidic environments, as well as an increase in mechanical strength when heated.
SiO2 content – 99.99%

The powder is intended for:
use as a filler for molding polymer press compositions used in the production of integrated circuits in microelectronics and ensures their operation in extreme conditions.
production of refractory products intended for laying out critical parts of glass furnaces: basins, ducts, screens, etc.
used as a material in the manufacture of thermal and corrosion protection elements in chemical engineering, and metallurgy, capable of operating at temperatures above 10000C in contact with molten glass and molten metals.
production of covers in the manufacture of high-temperature induction furnaces.
Monga chinthu chofunikira pamakampani a semiconductor komanso gawo la kuwala, migolo ya quartz yosakanikirana ili ndi mtengo wofunikira wogwiritsira ntchito komanso chiyembekezo chachitukuko. Mwa kukhathamiritsa njira zopangira ndikuwongolera zinthu zabwino, tikhoza kukwaniritsa zosowa za magawo osiyanasiyana ndikulimbikitsa chitukuko ndi zatsopano za mafakitale okhudzana nawo.
Kodi Fused Silica Barrels ndi chiyani 
Zosakaniza za Silica Barrels: Chinthu chofunikira chomwe chimagwiritsidwa ntchito mumakampani a semiconductor okhala ndi chiyero chambiri komanso kukana kutentha kwambiri
Ubwino wa migolo ya silika yosakanikirana ndi yotani?
- Kukhazikika kwa kutentha kwakukulu: Kutha kupirira kutentha kwambiri popanda kusungunuka kapena kupunduka - Chemical inertness: Good dzimbiri kukana zosiyanasiyana mankhwala - Kuwonekera kwa kuwala **: Ili ndi mawonekedwe owoneka bwino kwambiri ndipo ndiyoyenera kuwongolera ndi kuzindikira. - Kukonzekera kolondola **: Ikhoza kukonzedwa bwino m'mawonekedwe osiyanasiyana kuti ikwaniritse zosowa zosiyanasiyana.
Kodi madera omwe amagwiritsidwa ntchito kwambiri ndi migolo ya silika yosakanikirana ndi iti?
- Kupanga kwa semiconductor **: amagwiritsidwa ntchito popanga zida zazikuluzikulu za zida za semiconductor monga makina a lithography ndi zida zowonda zoyika mafilimu. - Zida zowonera **: oyenera kupanga magalasi ndi zida zowoneka bwino za zida zowonera monga ma telescope ndi ma spectrometer. - Kuyesera kwa mankhwala **: monga zotengera zosungiramo zopangira mankhwala, amapirira kutentha kwambiri ndi zinthu zowononga.
Kodi njira yopangira migolo ya silika yosakanikirana ndi chiyani?
- Kusungunuka **: Kutenthetsa zinthu za silika zoyera kwambiri mpaka kusungunuka. - Kuumba **: Kuumba silika wosungunuka kukhala mbiya yowoneka bwino pogwiritsa ntchito nkhungu kapena ukadaulo wowongolera bwino. - Kupitilira**: Kuchotsa kupsinjika kwamkati mwa kuwongolera kutentha ndi nthawi kuti muchepetse kutentha komanso kukhazikika kwa mbiya ya quartz yosakanikirana..
Ndi mavuto ati omwe amapezeka ndi mayankho a migolo ya quartz yosakanikirana? .
- Thermal shock cracks**: Ming'alu imawonekera pansi pakusintha kwachangu kwa kutentha. - Yankho**: Konzani njira yolumikizira kuti muwongolere kukhazikika kwamafuta a mbiya ya quartz yosakanikirana. - Kukokoloka kwa Chemical**: Kuwonongeka kwa zinthu zowononga monga ma asidi amphamvu ndi ma alkalis. - Yankho**: Sinthani zokutira pamwamba kapena sankhani zida zokhala ndi dzimbiri zolimba. - Kusalondola kwa mawonekedwe**: Kupatuka kwa mawonekedwe kapena kusakhazikika komwe kumachitika panthawi yopanga. - Yankho**: Konzani njira zopangira, limbitsa kulamulira khalidwe, ndikuwonetsetsa kulondola kwazinthu. - Mavuvu amkati **: Mipweya yomwe ili muzinthuzo imatsekeredwa mumgolo, kukhudza moyo wake wautumiki ndi magwiridwe antchito. - Yankho**: Konzani njira yoyeretsera zinthu, kuchepetsa zotsalira za gasi, ndi kukonza zinthu zabwino.
Ndi njira yotani yokonzera mbiya ya quartz yosakanikirana?
- Kuyeretsa pafupipafupi**: Gwiritsani ntchito choyeretsa chapadera kuti muyeretse pamwamba kuti muchotse zinyalala ndi dothi. - Pewani kugunda **: Gwirani mosamala ndikupewa kugundana ndi zinthu zolimba kuti mupewe kukwapula kapena kuwonongeka. - Kusungirako koyenera**: Pewani kukhudzidwa kwa nthawi yayitali ndi kutentha kwambiri kapena malo achinyezi, ndikusankha malo owuma ndi mpweya wabwino. - Kuyendera pafupipafupi **: Nthawi zonse fufuzani pamwamba pa ming'alu kapena kuwonongeka, ndi kukonza kapena kuyisintha munthawi yake
