Graphite block, as the name implies, is a piece of graphite, the shape is divided into two kinds: round, square. We are engaged in graphite industry for ten years, the graphite block produced has hundreds of tons, the graphite block is very widely used, because graphite has many excellent characteristics: high temperature resistance, melting point 3800 degrees, boiling point 4000 degrees, good electrical conductivity, corrosion resistance and acid and alkali resistance, is a more stable substance in nature. Therefore, graphite is an excellent material.

Then, the graphite blocks cut from graphite are also very widely used. The biggest use of graphite block is in the semiconductor field, but it is also widely used in solar cells, sensors, nanoelectronics, high performance nanoelectronic devices, composite materials, field emission materials, etc. Graphite blocks are mainly used in metallurgical furnaces such as silicon carbide furnaces, graphitization furnaces, resistance furnaces as furnace linings and conductive materials, and impermeable graphite heat exchangers. It is widely used in various fields such as electronics, metallurgy, chemical industry, steel, etc. The products have excellent quality and stable performance.

Graphite has the advantages of small resistance coefficient, high temperature resistance, corrosion resistance, good thermal shock resistance, electrical conductivity, small thermal expansion coefficient, self-lubrication, easy to precision machining, etc. It is the ideal crucible boat for inorganic non-metal, single crystal furnace heater, EDM graphite, sintering mold, electron tube anode, metal coating, graphite crucible for semiconductor technology, graphite anode for emission electron tube, gate tube and mercury arc rectifier graphite anodes for emitting electron tubes, gate tubes and mercury arc rectifiers, etc.

Graphite blocks can also be used in graphite equipment

What is the role of graphite blocks in graphite equipment? The graphite blocks used in the production of graphite heat exchanger and graphite absorber are called graphite heat exchanger blocks and graphite absorber blocks. Generally speaking, the pores of the purchased graphite blocks contain a small amount of water, so they need to be dried first to make the water evaporate, this process is carried out in an electric oven, the temperature is controlled within 350℃, the drying time is about 1-2 hours. Graphite heat exchanger, graphite absorber equipment because the heat exchanger block absorber block only bear pressure and for the whole structure, no glue joints, and thus high structural strength, good impact resistance, in graphite equipment plays an important and irreplaceable role.
