Tungsten Crucibles are vital for sapphire crystal growth and are widely used in high-temperature environments such as vacuum furnaces. These crucibles are highly durable and capable of withstanding extreme temperatures, making them ideal for sapphire growth, rare earth smelting, and coating applications. Their precision manufacturing ensures airtight seals, preventing contamination and maintaining adequate vacuum conditions during processing. Tungsten crucibles come in various shapes, including circular, square, rectangular, and V-shaped, each requiring specialized production methods like sintering, welding, stamping, or spinning. Despite their durability, repeated use can cause brittleness, making proper handling and sealing essential to prolong their lifespan.

Thin Film Materials Engineering (TFM) offers expertly crafted tungsten crucibles designed specifically for sapphire growth and other high-temperature applications. Our products are manufactured precisely using advanced techniques, ensuring durability and optimal performance in vacuum furnaces.
