Why Use Quartz Crucibles for Monocrystalline Silicon

Reasons for using quartz crucibles in the production of monocrystalline silicon mainly include the following:

High Purity

Quartz crucibles are made from high-purity quartz sand, ensuring that the crucible does not introduce impurities during the growth of monocrystalline silicon, thus guaranteeing the high purity of the monocrystalline silicon.

High Temperature Resistance

Quartz crucibles have excellent temperature resistance and can be used at temperatures up to 1450°C, which meets the high-temperature requirements for the growth of monocrystalline silicon.

High Dimensional Accuracy

Quartz crucibles can be made into large sizes with high precision, which is necessary for pulling large diameter monocrystalline silicon rods.

Good Insulation

Quartz crucibles have good insulation properties, which help maintain the stable temperature required during the growth of monocrystalline silicon.

Stable Quality

The production technology of quartz crucibles is very mature, ensuring the stability of the crucible's quality and reducing uncertainties in the production process.

Chemical Stability

Except for hydrofluoric acid, quartz crucibles do not react with other acids, helping to maintain the stability of the growth environment.

As one of leading quartz crucible suppliers, quartz crucible for silicon form DSTC is high quality and suitable for Monocrystalline Silicon.
