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.
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.

Quartz, the main component of glass, has a variety of different applications in various industries such as construction granulates and solar panels. It's a hard, crystalline mineral made up of silicon and oxygen atoms, and it's also the second most widely available mineral in the earth's crust after the feldspar Quartz mineral has hexagonal-shaped crystals. The color range for quartz is massive. This adaptable mineral is both long-lasting and chemically inert, with high heat resistance and electrical qualities. We source the majority of our quartz minerals from the regions of Rajasthan, Bihar and Andhra Pradesh. It is an extremely useful mineral in the manufacturing of solar panels, semiconductors and electronics, aluminium and steel alloys, and also in the construction sector, after being transformed into silicon (Si) through gaseous reduction at high temperatures. The physical properties of the quartz mineral are chemical inertness, thermal stability and electrical properties. It is also known for its hardness and it ranks 7 on the Mohs scale. Our high-purity quartz mineral finds its usage in the manufacturing of the casting of silicon for photovoltaic cells that make up solar panels and semiconductor components. Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Within the sector of aluminium and iron & steel industries, quartz pebbles once converted to silicon, are critical components in the production of ferro-alloys and silicon for aluminium alloys and silicone. Further, in the refractories, high-grade quartzite-based silica minerals have been used in the fabrication of linings for the coreless induction furnaces for melting and retaining iron for decades. We at Aryan Tiles will keep its development efforts focused on developing new markets for its high-purity quartz products that promote the usage of renewable energy sources like solar power cells.
Features Of Quartz Quartz is very common in sedimentary rocks such as sandstone. It is composed of Silicon and oxygen atoms. It is closest to pure chemical compound and has constant physical properties. Quartz strength and non-reactive properties make it indispensable ingredient in the production of thousand of everyday products. Application Drilling Ceramics Paints Glass
