Elmet provides a variety of molybdenum crucibles for sapphire growth furnaces, as well as many other components for these furnaces. Corrosion resistance, creep resistance, and high temperature performance make molybdenum and tungsten crucibles ideal for use in high temperature crystal growth processes. Crystal growth is at the foundation for many cutting edge technologies such as sapphire touch screens, LED lighting parts, solar cells and high power lasers. Elmet is continually improving manufacturing and materials processes to meet the evolving requirements of this industry. From raw material to finished product, Elmet’s integrated manufacturing process, quality systems and metallurgical expertise ensure we deliver quality components for the crystal growth industry.
In the last 10 years, Elmet has invested in one of largest US-based hot spinning machines to make large molybdenum hot spun crucibles and other seamless refractory products. Our hot spinning operation has the capacity to spin up to 1/2 “ thick molybdenum blanks as large as 62” in diameter.
PRESSED AND SINTERED CRUCIBLES
- Powder is pressed and sintered to final shape geometries to meet the requirements of each furnace design
- Large molybdenum plate blanks are hot spun formed to the specified product geometry
- Elmet has experience in a wide variety of molybdenum crucible sizes up to 20″ diameter
- Material blanks are machined to the final product geometries
