Fused silica ceramics are manufactured using slip casting which combines elements of ceramic fabrication and powder metallurgy, which are homogeneous and the surface are smooth and less pore. Regarding the customer demands, the surface can be further glazed to shine like jade.
Robuster offers a wide product range of fused silica crucibles and trays for numerous applications in corrosive and high temperature environments. Specially quartz trays is a thermal ceramics products for the aluminium & non-ferrous industry.
Custom specifications are available.
A crucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot.
Graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and other metals.
Quartz crucible has the advantages of high purity ,high temperature resistance, with big size ,good thermal insulation, economization on energy ,quality stability etc.
Fused quartz crucibles are used in the manufacture of silicon metal for semiconductor wafer applications and polysilicon. In order to produce high quality wafers, starting materials are added to a crucible heated to high temperatures and pulled from the melt as a single crystal. Fused Quartz is one of the few materials that can combine the high purity and high temperature properties required for this process.
GW offers graphite crucibles & Ceramics (Quartz) crucibles in different sizes and types. Whenever you need crucibles, just feel free to contact us, and we will reply you in a shortest time.
We could supply kinds of laboratory quartz glasswares according to customers' requirements, including quartz boat, quartz beaker, quartz conical flask, quartz crucible, etc.
