1. Thermal stability: According to the use conditions of graphite crucible for rapid heating and cooling, special design is carried out to ensure the reliability of quality; 2. Corrosion resistance: The uniform and fine matrix design delays the corrosion of the crucible; 3. Impact resistance: The thermal shock strength that the graphite crucible can withstand is extremely high, so any process can be carried out with confidence; 4. Acid resistance: the addition of special materials significantly improves the quality of graphite crucibles, has excellent performance in terms of acid resistance indicators, and greatly prolongs the service life of graphite crucibles; 5. High thermal conductivity: The high content of carbon ensures good thermal conductivity, shortens the dissolution time, and significantly reduces fuel consumption or other energy consumption; 6. Control of metal pollution: Strict control of material composition ensures that the graphite crucible does not pollute the metal during dissolution; 7. Quality stability: The technical process and quality assurance system of the high-pressure forming method more fully guarantee the stability of the quality.
