R60702 Zirconium Crucible Solution for Industrial/Laboratory Use

R60702 material zirconium crucibles refer to container products made of R60702 grade zirconium alloy through processes such as stamping, spinning and welding. They are mainly used in scenarios such as melting, refining, heat treatment of metal and non-metal materials, and chemical experiments. As a classic pure zirconium-based alloy grade, R60702 relies on excellent high-temperature resistance (can work stably below 800℃ for a long time and withstand 1000℃ for a short time), outstanding corrosion resistance (has extremely strong resistance to most acids, alkalis, salts, molten metals and high-temperature gases, especially stable in strong corrosive chemical media), as well as the characteristics of pure material without impurity pollution. It has become a core equipment accessory in fields with high requirements for container materials and performance, such as nuclear industry material preparation, high-end chemical reactions, special metal melting, and precision electronic material research and development. It is especially suitable for material processing needs with strong corrosion, high temperature and high purity requirements.

Characteristics

Excellent High-Temperature Resistance

R60702 zirconium alloy has a melting point of up to 1852℃, can work stably below 800℃ for a long time, and withstand 1000℃ for a short time, with no deformation or melting risk, adapting to medium and high-temperature working conditions.

Extreme Corrosion Resistance

It has extremely strong stability in harsh environments such as strong acids (including most strong acids except hydrofluoric acid), strong alkalis, molten salts, high-temperature oxidizing atmospheres and various molten metals. The dense oxide film formed on the surface can effectively resist corrosion and not pollute materials, especially suitable for strong corrosive medium processing scenarios.

Pure Material Without Impurities

Follows R60702 grade standard, total Zr+Hf content ≥99.2%, extremely low impurity content, will not chemically react with melted or reaction materials, ensuring material purity, especially suitable for high-precision experiments and high-end material preparation.

Uniform and Stable Heat Conduction

R60702 zirconium alloy has moderate and uniform thermal conductivity, which can make the materials in the crucible heated evenly, avoid material deterioration or crucible damage caused by local overheating, and improve melting/reaction effect.

Good Structural Strength

After stamping, spinning or welding forming, the structure is firm. R60702 alloy itself has excellent mechanical properties, strong impact resistance and deformation resistance, and its service life is much longer than that of crucibles made of ordinary ceramics, quartz and other materials.

Easy Processing and Customization

R60702 zirconium alloy has excellent processing performance, can be made into crucibles of different shapes and sizes through various processes, supports personalized processing such as welding lug handles and surface coating, and adapts to the needs of different equipment and application scenarios.

Production Process

Raw Material Preparation: Zircon sand is processed through mineral processing, chlorination and reduction processes to extract high-purity sponge zirconium, which is then smelted multiple times in a vacuum arc furnace to produce zirconium ingots that meet R60702 grade standards (uniform composition and qualified impurity content), and then rolled into R60702 zirconium plates/zirconium strips.
Blank Processing: According to the crucible size requirements, the R60702 zirconium plates/strips are cut to obtain blanks that meet the specifications; the blanks are subjected to surface pretreatment (pickling, grinding) to remove oxide scale and impurities.
Forming Processing: Select the corresponding process according to the crucible type - stamping forming is used for small and medium-sized regular crucibles, spinning forming is used for medium and large-sized and special-shaped crucibles, and welding forming is used for complex structure crucibles, ensuring that the crucible shape is regular and the wall thickness is uniform.

Vacuum Annealing: Put the formed R60702 zirconium crucible into a vacuum annealing furnace, and treat it at a specific temperature and holding time to eliminate processing internal stress, improve the high-temperature resistance and toughness of R60702 alloy, and reduce use deformation.
Finishing Processing: Trim, shape and surface treat (pickling, polishing, etc.) the annealed R60702 zirconium crucible; perform customized processing such as welding lug handles and drilling if necessary; finally conduct non-destructive testing (appearance inspection, wall thickness inspection, composition re-inspection, etc.) to ensure that the product quality meets R60702 grade standards and customer requirements, with material inspection report and quality certificate attached.
