Molybdenum-Titanium-Zirconium Alloy High-Temperature Sintering Boat

Mo-Ti-Zr alloy sintering boats are produced through powder metallurgy, followed by precise forming, welding, and machining to meet tight dimensional tolerances. Their enhanced performance under extreme conditions makes them essential components in advanced materials manufacturing and thermal processing industries.

Classification:


  • Molybdenum-Titanium-Zirconium (Mo-Ti-Zr) alloy sintering boats, also known as high-temperature crucibles or trays, are specialized refractory containers designed for use in extreme thermal environments. This ternary alloy combines the high melting point and strength of molybdenum with the enhanced oxidation resistance and microstructural stability provided by titanium and zirconium additives, making it ideal for demanding sintering, annealing, and vacuum heat treatment processes.

    Key Features:

    • Material Composition: Typically Mo-based alloy with small additions of Ti and Zr to improve high-temperature oxidation resistance, grain stability, and mechanical strength.

    • High Melting Point: Withstands temperatures above 1800°C in vacuum or inert atmospheres.

    • Excellent Structural Integrity: Maintains shape and strength under long-term thermal cycling.

    • Improved Oxidation Resistance: Compared to pure molybdenum, Mo-Ti-Zr alloy resists surface degradation at elevated temperatures.

    Applications:

    • High-temperature sintering of ceramics, rare earths, and powder metallurgy components

    • Vacuum heat treatment of metal parts

    • Crystal growth processes (e.g., sapphire, garnet)

    • Annealing and brazing in hydrogen or inert gas furnaces

    • Carrier boats for semiconductor and electronic component processing

    Advantages:

    • Superior thermal shock resistance and dimensional stability

    • Longer service life than conventional molybdenum crucibles

    • Low contamination—ideal for high-purity material processing

    • Customizable sizes and shapes for various furnace configurations
