Tantalum Furnace Parts

1. Product name: Tantalum Furnace Parts

Tantalum is easy to process and form and can be used as support accessories, heat shields, heaters, and heat sinks in high-temperature vacuum furnaces. The high melting point metals tantalum is used as tantalum furnace parts in the form of wires, strips, and plates. They have many structural forms but minimize the contact with refractory materials and insulating materials to avoid chemical reactions and reduce the heater's performance life. In the equipment for preparing various inorganic acids, tantalum furnace parts can be used to replace stainless steel, and the service life can be increased by dozens of times compared with stainless steel.

2. Most vacuum-furnace hot zones consist of four major components: the heating elements and the details on which they are mounted; the insulation package (or heat shields); a surrounding structure that supports the heating elements and insulation package; and a hearth that supports the load during processing.

3. Features Of Tantalum Furnace Parts

For vacuum furnaces with a rated temperature of 1000℃~1600℃ (a few can reach 1700℃), molybdenum wire or molybdenum sheet can be selected as the heating element material as the heating element; when the temperature is lower than 2200℃, the refractory metal tantalum can be selected as the heating element Material, the processing performance of tantalum is better than that of molybdenum, and it can be welded. During processing, scraps can be recycled, but they cannot be used in a hydrogen atmosphere. However, tantalum furnace parts are expensive and are generally only used as a heating element material in special cases; tungsten is rated for use in temperature. The rated temperature of a tungsten sheet can reach 2400-2500 °C, but due to the poor impact resistance of the tungsten sheet, the texture is very brittle, and cracks are prone to occur during processing, so the yield is very low.
