Entire Frosted Quartz Crucible– Secret Specs

Product and Pureness

The crucible is made from high-purity artificial integrated quartz. It includes over 99.99% SiO ₂. This guarantees excellent resistance to chemical reactions at high temperatures. The material stays stable even when subjected to hostile compounds like acids or molten metals.

Surface area End up

The whole external surface features a consistent frozen structure. This coating boosts grasp during handling and reduces the threat of sliding. The inner surface area remains smooth to support clean melting and very easy pouring.

Temperature Resistance

This crucible can handle continual consume to 1200 ° C(2192 ° F). It withstands temporary direct exposure up to 1400 ° C (2552 ° F) without splitting or deforming. Thermal shock resistance is solid due to low thermal development of quartz.

Measurements and Capability

Requirement sizes range from 50 mL to 2000 mL. Wall density is consistent throughout all versions, normally between 2 mm and 5 mm, relying on capability. Each unit is precisely formed with straight wall surfaces and a level bottom for secure placement on home heating surface areas.

Production Refine

Generated through flame-fusion or electric fusion methods under stringent quality assurance. Every crucible undergoes aesthetic evaluation and dimensional checks. No binders or additives are utilized during production, ensuring pure quartz composition.

Applications

Suitable for lab melting, crystal growth, semiconductor handling, and high-temperature analysis. Typically used with precious metals, oxides, and specialized glasses. Its inert nature avoids contamination of sensitive materials.

Product packaging and Handling

Each crucible comes separately wrapped in safety foam and crammed in a stiff cardboard box. Handle with tidy handwear covers to stay clear of surface area oils. Store in a completely dry, dust-free setting before use. Prevent abrupt temperature modifications throughout operation to preserve honesty.

5 FAQs of Whole Frosted Quartz Crucible

Frequently Asked Questions About Whole Frosted Quartz Crucibles

What is a whole frosted quartz crucible?

A whole frosted quartz crucible is made from high-purity fused quartz. Its inner and outer surfaces are uniformly frosted, not smooth. This design helps reduce light reflection and improves thermal stability during high-temperature processes like crystal growth.

Why choose a frosted surface over a clear one?

The frosted surface scatters light evenly. This lowers hot spots inside the crucible. It also supports more stable temperature distribution. As a result, silicon crystal growth becomes more consistent and reliable.

What temperatures can it handle?

These crucibles work well at temperatures up to 1,200°C continuously. They can briefly withstand even higher heat, close to 1,650°C. Their strong thermal shock resistance makes them ideal for repeated heating and cooling cycles.

Is it safe for semiconductor manufacturing?

Yes. Whole frosted quartz crucibles contain very low levels of metal impurities. They meet strict purity standards required in semiconductor and solar-grade silicon production. Their clean composition prevents contamination of molten silicon.

How long does it last?

Lifespan depends on operating conditions. In standard Czochralski (CZ) crystal pulling setups, one crucible typically lasts through one or two full runs. Proper handling and controlled heating extend its usable life. Avoid sudden temperature changes to prevent cracking.
