High purity
Can be made according to the requirement of our customers high purity
Crucible, the range of our products is from 18-24 inches.
We use high-temperature arc-melting and coating method.
To ensure the high purity of quartz crucible, minde insists to use high
Purity raw material which is import from u.S and dose not add any domestic
Quartz sand.
Quartz crucible can be made according to the requirement of our customers.

Fused silica is a glass consisting of pure silica (SiO2) in amorphous form. Fused quartz has high working and melting temperatures, making it less desirable for most common applications. Fused silica is a glass consisting of pure silica in amorphous form. Applications â?? Electrode flux coating Optical components
Quartz is a hard, crystalline mineral composed of silicon dioxide. Quartz is the second most abundant mineral in Earth\'s continental crust. We provide different forms of quartz such as lumps, granules and powder at customer specified sizes. Applications â?? Construction Water purification Agro Industry

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.

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.
