Zirconium 702 Crucible

Descrizione di prodotto

Overview

Zirconium 702 Crucible is a high-temperature corrosion-resistant vessel made of 99.2% pure industrial zirconium processed with a purity of ≥, which combines excellent chemical stability, excellent high temperature and thermal shock resistance, and low neutron absorption cross-section, making it an ideal alternative to traditional crucibles such as graphite and platinum.

The use scenarios cover high-temperature melting of precious metals and special materials, semiconductor single crystal crystallization, nuclear industry experiments, chemical high-purity synthesis and laboratory thermal analysis, and other severe working conditions, especially suitable for high-purity processes in vacuum or inert atmosphere, effectively avoiding material pollution.

In addition, as a professional supplier with many years of experience in the production and export of non-ferrous metals, we can also provide customers with tungsten crucibles, molybdenum crucibles, titanium crucibles, tantalum crucibles, etc. If you are interested, please feel free to contact us by email.

Zirconium 702 Advantages

• Zirconium 702 has a corrosion resistance that far exceeds that of stainless steel and titanium alloy in high-temperature strong acid, strong alkali, and molten salt environments, and is almost not corroded and has a long service life.
• It has good strength and dimensional stability at high temperatures, is resistant to thermal shock, is not easy to deform or crack, and is suitable for severe working conditions such as high-temperature smelting, sintering, and calcination.
• It does not react with high-purity metals, special crystals, precious metals, etc., at high temperatures, and has no impurity precipitation, ensuring the purity of melting products, which is the first choice for high-purity processes.
• Zirconium 702 has good plasticity and can be made into seamless, thin-walled, large-size, special-shaped crucibles with better sealing and consistency than many brittle ceramic crucibles.
• It is especially suitable for precious metal smelting, special ceramics, crystal growth, chemical high-purity synthesis, scientific research experiments, and other fields with extremely high purity and corrosion resistance.

Zirconium Crucible Application

1. Chemical industry and laboratory applications
This is the most important application area for zirconium 702 crucibles, especially for the treatment of highly corrosive media.
Zirconium 702 Crucible is widely used in chemical equipment for the manufacture and production of strong acids such as hydrochloric acid, sulfuric acid, acetic acid, etc., such as reactor liners, evaporator heating tubes, etc.
As a high-purity experimental vessel, it is used for high-temperature, highly corrosive chemical reactions and sample digestion to ensure the accuracy of experimental results and avoid contamination of samples by container materials.
2. High-temperature materials and metallurgy
Zirconium Crucible is specifically designed to smelt precious metals such as platinum, palladium, rhodium, and iridium and their alloys.
It is used to prepare superalloys and special alloys with extremely high purity requirements to ensure that the alloy components are not contaminated.
3. Nuclear industry applications
Equipment containers for the manufacture and treatment of nuclear waste, resistant to corrosion and degradation of radioactive materials.
4. Medical and bioengineering
For the manufacture of orthopedic implants (e.g., artificial joints, bone plates) and corrosion-resistant surgical instruments that require long-term implantation in the human body, meeting relevant biocompatibility standards.

Processing

1. Forged seamless crucible (preferred for high demands)
Raw material preparation → vacuum melting → billet making → hot forging forming → machining finishing → vacuum annealing → surface treatment → quality inspection out of the factory
2. Welding crucible (large size / thin wall customization)
Raw material preparation → Vacuum melting → Rolled plate/strip → Coil bevel → Argon arc welding → Weld treatment → Vacuum annealing → Machining finishing → Surface treatment → Quality inspection and leaving the factory
