Pure Titanium/Titanium Alloy Crucibles for Industrial/Laboratory Use

Titanium crucibles are container-like products made of metallic titanium or titanium alloy through stamping, spinning, welding and other processes. They are mainly used for melting, refining, heat treatment of metal and non-metallic materials, as well as chemical experiments. With excellent high-temperature resistance (can work stably below 600℃ for long-term use and withstand 800℃ for short-term use), extreme corrosion resistance, and pure material free from impurity contamination, they have become core equipment accessories in fields with strict requirements for container material and performance, such as aerospace material R&D, electronic material preparation, chemical experiments, and precious metal melting. They are especially suitable for material processing needs under strong corrosion media and high-temperature environments.

    Characteristics

    01

    Excellent High-Temperature Resistance

    Melting point up to 1668℃. Pure titanium crucibles can work stably below 600℃ for long-term use, while titanium alloy crucibles (GR5) can work stably at 600-800℃ for long-term use and withstand higher temperatures for short-term use without deformation or melting risk.
    advantage-2
    02

    Extreme Corrosion Resistance

    Highly stable in harsh environments such as strong acids (except hydrofluoric acid), strong alkalis, molten salts, and high-temperature oxidizing atmospheres. The dense oxide film formed on the surface can effectively resist corrosion without contaminating materials.
    advantage-2
    03

    Pure Material Free from Impurities

    Pure titanium content ≥99.5% with extremely low impurity content. It will not undergo chemical reactions with melted or reacted materials, ensuring material purity. Especially suitable for high-precision experiments and high-end material preparation.
    advantage-2
    04

    Uniform and Stable Heat Conduction

    Titanium has moderate and uniform thermal conductivity, enabling uniform heating of materials inside the crucible, avoiding material deterioration or crucible damage caused by local overheating, and improving melting/reaction effects.
    advantage-2
    05

    Good Structural Strength

    After stamping, spinning or welding forming, it has a firm structure, strong impact resistance and deformation resistance, with a service life much longer than ordinary ceramic, quartz and other material crucibles.
    advantage-2
    06

    Easy Processing and Customization

    Can be made into crucibles of different shapes and sizes through various processes, supporting personalized processing such as welded ear handles and surface coating to meet the needs of different equipment and application scenarios.
    advantage-2

    Production Process

    1. Raw Material Preparation: High-purity sponge titanium is extracted from titanium concentrate through beneficiation, chlorination and reduction processes. It is then smelted multiple times in a vacuum arc furnace to produce titanium ingots with uniform composition and low impurity content, which are further rolled into titanium plates/foils.
    2. Blank Processing: According to the crucible size requirements, titanium plates/foils are cut to obtain blanks that meet specifications; the blanks undergo surface pretreatment (pickling, grinding) to remove oxide scale and impurities.
    3. Forming Processing: Corresponding processes are selected according to the crucible type—small and medium-sized conventional crucibles adopt stamping forming, medium and large-sized as well as special-shaped crucibles adopt spinning forming, and complex-structured crucibles adopt welding forming to ensure regular crucible shape and uniform wall thickness.
    4. Vacuum Annealing: The formed titanium crucible is placed in a vacuum annealing furnace for treatment at a specific temperature and holding time to eliminate internal processing stress, improve material's high-temperature resistance and toughness, and reduce deformation during use.
    5. Finishing Processing: The annealed titanium crucible undergoes trimming, shaping, surface treatment (pickling, polishing, etc.), and customized processing such as welded ear handles and drilling if necessary; finally, non-destructive testing (appearance inspection, wall thickness inspection, etc.) is performed to ensure qualified product quality, with material inspection report and quality certificate attached.
