Description

Graphitization and purification integrated furnace

Technical Field

The invention relates to a graphitization and purification integrated furnace.

Background

The demand of the market for graphite materials is higher and higher, so the common graphite materials need further treatment. The treatment of ordinary graphite is mainly divided into two aspects, namely graphitization and purification.

The graphitization treatment method is high-temperature calcination, and the graphitization can improve the performance of the graphite material and discharge a small amount of impurities. The purification treatment method is that the purification gas is introduced to fully contact with the common graphite in a high-temperature environment, and the purification gas reacts with impurities contained in the common graphite material to generate gas and is discharged in the contact process, so that the aim of purifying the material is fulfilled.

Currently, for example, the semiconductor industry, consumes large quantities of high purity graphite materials in the manufacture of semiconductors. The functions of the existing high-temperature furnace in the market are single, and only graphitization or purification can be carried out. The pure graphitization high-temperature furnace cannot rapidly discharge impurities, the whole structure of the furnace is not corrosion-resistant and cannot be directly purified, the pure graphitization furnace cannot rapidly discharge impurities, and the furnace temperature is too low to be directly graphitized.
