Graphite Crucible Furnace for Sale 

Graphite crucibles for melting platinum has good thermal conductivity and high temperature resistance. The thermal expansion coefficient is small in the process of high temperature use, and also has certain anti-strain properties for hot and cold.The corrosion resistance of acid and alkaline solution,so PDSKY graphite crucible crucibles for melting platinum have strong and excellent chemical stability.       Product Feature crucibles for melting platinum feature:   1. High temperature: the melting point of graphite crucible is 3850, the boiling point is 4250, even after the ultra-high temperature arc ignition, the loss of weight is small, and the thermal expansion coefficient is small.The intensity of the graphite increased with the temperature, and the graphite strength doubled in 2000 2.The conductivity of crucibles for melting steel is a hundred times higher than non-metallic ore.Ther…
