Product Series

Conductive Plate for MOCVD Heaters

Product Introduction

Molybdenum has a melting point as high as 2,600°C, good high-temperature strength, low pollution, good machinability, good thermal conductivity, and maintains good mechanical properties at high temperatures. As a result of these characteristics, it is used in various high temperature components, including molybdenum crucibles, molybdenum core rods, molybdenum rings, and molybdenum tubes.

The molybdenum crucible has a heat-resistant temperature of 2,200°C and a density of 10.0g/cm3 or more.3




Product Application

The large-size graphite heating element crystal growth process is currently the most common method for sapphire crystal growth; this approach has higher performance requirements for molybdenum crucibles. These need to be repeatedly heated and cooled in an environment at 2,200°C, and can guarantee the service life requirements of furnaces. The heat exchange crystal growth process also requires a molybdenum crucible formed by spinning, the process of which forms a thin wall. It is also necessary to ensure sufficient high-temperature strength and creep resistance during single crystal melting and solidification to prevent cracking.

All crystal growth processes require high purity of the crucible to ensure that the crystal remains free from impurities.

Product Specifications

Purity is greater than 99.97%.

Spinning molybdenum crucibles have a density in excess of 10.2 g/cm3 and a diameter of up to 600 mm.

Pressed and sintered molybdenum crucibles have a density over 10.0g/cm3 and a diameter of up to 1,000 mm.

We can provide pressed and sintered molybdenum crucibles in rough and finished state depending on customer requirements.
