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.
Ma ke ʻano he kumu nui i ka ʻoihana semiconductor a me ka māla optical, ʻO nā pahu quartz fused he waiwai hoʻohana koʻikoʻi a me nā manaʻo hoʻomohala. Ma ka hoʻonui ʻana i ke kaʻina hana a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka huahana, hiki iā mākou ke hoʻokō maikaʻi i nā pono o nā māla like ʻole a hāpai i ka hoʻomohala ʻana a me ka hana hou o nā ʻoihana pili.
He aha ka Fused Silica Barrels 
Nā Barela Silica Hui: He mea koʻikoʻi i hoʻohana ʻia i ka ʻoihana semiconductor me ka maʻemaʻe kiʻekiʻe a me ke kūpaʻa wela maikaʻi
He aha nā pōmaikaʻi o nā pahu silica fused?
- Paʻa wela kiʻekiʻe: Hiki ke kū i nā wela kiʻekiʻe loa me ka hoʻoheheʻe ʻole ʻana a i ʻole deforming - ʻO ka inertness kemika: Kūleʻa maikaʻi i ka corrosion i nā ʻano kemika - ʻO ka ʻike maka**: Loaʻa iā ia ka ʻike ʻike maikaʻi loa a kūpono no ka hoʻoili ʻana a me ka ʻike. - Ka hana pololei**: Hiki ke hana pololei ʻia i nā ʻano like ʻole e hoʻokō i nā pono like ʻole.
He aha nā wahi noi nui o nā pahu silica fused?
- Hana semiconductor**: hoʻohana ʻia e hana i nā ʻāpana koʻikoʻi o nā mea hana semiconductor e like me nā mīkini lithography a me nā mea hoʻoheheʻe kiʻiʻoniʻoni lahilahi. - Nā mea kani ʻōpika**: kūpono no ka hana ʻana i nā lens a me nā ʻāpana optical o nā mea ʻike e like me nā telescopes a me nā spectrometers. - Nā hoʻokolohua kemika**: e like me nā pahu mālama no nā reagents kemika, kū lākou i nā wela kiʻekiʻe a me nā mea corrosive.
He aha ke kaʻina hana o nā pahu silica fused?
- hehee**: Hoʻomaʻamaʻa i nā mea silica maʻemaʻe kiʻekiʻe i kahi kūlana hoʻoheheʻe. - Molina**: Ka hoʻoheheʻe ʻana i ka silica i hoʻoheheʻe ʻia i loko o ke ʻano barela me ka hoʻohana ʻana i ka ʻenehana mīkini hana pololei. - Hoʻopili**: Hoʻopau i ke koʻikoʻi o loko ma o ka hoʻomalu ʻana i ka mahana a me ka manawa e hoʻomaikaʻi ai i ke kūpaʻa wela a me ke kūpaʻa o ka pahu quartz fused..
He aha nā pilikia maʻamau a me nā hoʻonā o nā pahu quartz fused? .
- Nā māwae haʻalulu wela**: ʻIke ʻia nā māwae ma lalo o ka hoʻololi wikiwiki ʻana o ka mahana. - Hoʻoholo**: E hoʻonui i ke kaʻina hana annealing e hoʻomaikaʻi i ka paʻa wela o ka pahu quartz fused. - ʻAi kemika**: ʻO ka pōʻino i hana ʻia e nā mea ʻino e like me nā waikawa ikaika a me nā alkali. - Hoʻoholo**: E hoʻomaikaʻi i ka uhi ʻana a i ʻole e koho i nā mea me ke kūpaʻa ʻoi aku ka ikaika. - ʻAʻole pololei ke ʻano**: ʻO ka hoʻokaʻawale ʻana a i ʻole ke ʻano like ʻole i ka wā o ka hana ʻana. - Hoʻoholo**: E hoʻonui i ka hana hana, hoʻoikaika i ka mana maikaʻi, a hōʻoia i ka pololei o ka huahana. - Nā ʻōhū o loko**: Hoʻopaʻa ʻia nā kinoea i loko o ka mea i loko o ka pahu, pili ana i kona ola lawelawe a me ka hana. - Hoʻoholo**: E hoʻonui i ke kaʻina hana hoʻomaʻemaʻe, hoemi i ke koena kinoea, a hoʻomaikaʻi i ka maikaʻi o nā mea.
He aha ke ʻano mālama o ka pahu quartz fused?
- Hoʻomaʻemaʻe mau**: E hoʻohana i kahi mea hoʻomaʻemaʻe kūikawā e hoʻomaʻemaʻe i ka ʻili e wehe i ka sediment a me ka lepo. - Hōʻalo i ka hui ʻana**: E mālama pono a pale aku i ka hui ʻana me nā mea paʻakikī i mea e pale ai i ka ʻili a i ʻole ka pōʻino. - Mālama pono**: E hōʻalo i ka ʻike lōʻihi i ka wela kiʻekiʻe a i ʻole ka ʻāina humid, a koho i kahi maloʻo a me ka ventilated wahi mālama. - Nānā mau**: E nānā mau i ka ʻili no nā māwae a poino paha, a hoʻoponopono a hoʻololi paha i ka manawa
