Description
Technical field
The present invention relates to the crucible product field, is a kind of 26 inches heavy wall quartz crucibles, its production method and production unit.
Background technology
Domestic chemical industry, the old technology of glass industry all are to use platinum crucible to melt raw material, because the market value of platinum is than higher, cause enterprise cost significantly to increase. can substitute the quartz crucible that has only of platinum crucible, because purity height, good stability, the price of quartz crucible are low.Nearly ten years quartz crucibles become the first-selected container of chemical industry, glass industry thawing raw material.But, when melting glass, industrial chemicals, in its raw material certain basic metal and alkaline-earth metal are arranged, inwall to quartz crucible has certain corrosion, but basic metal or alkaline-earth metal as additive must join in the raw material, the sidewall of crucible of prior art is thin, can't satisfy the production needs, thus present stage manufacturer often use expensive platinum crucible, give to produce and safety is brought a lot of unnecessary troubles.
Increase the access times of quartz crucible for the wall thickness that can only thicken crucible work-ing life that prolongs quartz crucible.As most of semicon industry Czochralski techniques (cz) pulling monocrystal silicon with the common thickness of quartz crucible all at 9 ~ 16mm, the maximum diameter of the quartz crucible of domestic production 24 inches (600 ~ 615mm). but the heavy caliber of using as chemical industry, glass industry, wall thickness, the at present domestic still blank out of quartz crucible that the life-span is long.
Domestic Crucible Making-machine all is the quartz crucible design according to pulling monocrystal silicon, it is little to found the chamber, and transformer is little, and main frame is little, melting time is not long. and the sidewall of crucible of making is thin, external diameter is little, can not solve glass, the requirement of big, the crucible wall thickness of volume, long service life when chemical industry is melted material.
