The High Temperature Purification Furnace produced by our company is mainly applied to the purification of high carbon powder, high purity graphite and high purity insulating materials. The made high purity graphite is widely used in graphite crucible, graphite protective shield, graphite boat in semiconductor production, heating element, heat insulation material and furnace structure in vacuum furnace and high temperature furnace, and used as the support material of silicon crystal rods and polysilicon furnace in solar cell production, etc. The high carbon powder is widely used in the anode material in lithium-ion batteries and lead-acid batteries, and the carbon increase agent in the alloy preparation and casting process.

The main purpose of high temperature graphitising and purification is to improve the purity and crystallinity of speciality graphites, high carbon powders, carbon felt insulation materials etc. for specific applications. High-temperature purification eliminates impurities and gases and further improves their physical and chemical properties, making them suitable for a wider range of industrial and scientific applications.
According to different customer needs, the company provides two heating methods, a variety of discharge methods of high-temperature purification furnace, and provide small batch sampling services and ingot furnace retrofit high-temperature purification furnace services.
Small batch high temperature purification service (not pass fluorine, chlorine gas body) please click " high temperature processing" to enter the relevant page.
Using this high-temperature purification method at 2850 ° C can be significantly removed from the special graphite Mg, Al, Ca, Mn, Fe and Ni and other impurity elements, so that the carbon content of 99.5%, after pre-treatment and adjust the protective gas process and the heating time, 3050 degrees Celsius temperature support, the carbon content of 99.9995%, <5ppm, even if it does not pass into the fluorine, chlorine gas body, we also have extensive experience in the 3000 degrees Celsius temperature, the carbon content of 99.9995%, <5ppm, even if it does not pass into the fluorine, chlorine gas body, we have a lot of experience in the purification process. We also have rich experience that the boron content in graphite heated at 3000°C is <0.01ppm, and has been fully practiced in industrialised furnace mass production.
