TevTech’s purification equipment utilizes a thermochemical process combining high temperatures with halogen gas to remove metallic impurities. In many applications impurities commonly found in graphite need to be removed in order to prevent migration and or doping of the components being processed. Many of these applications require graphite products with total trace impurities of less than 5 parts per million (5 PPM). TevTech purification systems routinely achieve this specification while utilizing a low halogen per pound of product processed ratio. The minimized halogen usage results in smaller on site storage requirements, reduces the impact on the equipment and reduces effluent streams.
The TevTech Graphite Purification furnaces use a unique heating element design and power distribution system that allows users to reduce high electric current losses.
