High Qulity Graphite Rod produced by Professional Manufacturer
Graphite rods commonly used in high temperature vacuum furnace heating body, the highest temperature up to 3000 ° C, and susceptible to oxidation at high temperatures, in addition to the vacuum outside, can only be used in a neutral atmosphere or reducing atmosphere. Smaller its coefficient of thermal expansion, thermal conductivity, electrical resistivity for the (8 ~ 13) × 10-6 Ω · m, processing than of SiC of MoSi2 rods, high temperature, extreme cold extreme heat resistance, the price cheaper.
