Duratight strictly select raw materials and adding antioxidants to make Crucible has the following characteristics

1. Thermal stability: the graphite crucible is specially designed to ensure the reliability of product quality according to the service conditions of rapid heating and rapid cooling.

2. Corrosion resistance: the uniform and fine matrix design delays the corrosion degree of the crucible.

3. Impact resistance: graphite crucible can withstand high thermal impact strength, so any process can be carried out safely.

4. Acid resistance: the addition of special materials can significantly improve the quality of the crucible, have excellent acid resistance index, and greatly extend the service life of the graphite crucible.

5. High thermal conductivity: high content of fixed carbon ensures good thermal conductivity, shortens dissolution time, and significantly reduces oil consumption or other energy consumption.

6. Control of metal pollution: the strict control of material composition ensures that the graphite crucible does not pollute the metal during dissolution.

7. Quality stability: the manufacturing technology and quality assurance system of high pressure forming method fully ensure the quality stability.
