Product Description

Graphite rods are often used as electric heaters in high-temperature vacuum furnaces, with a maximum service temperature of ***0 ° C. they are easy to be oxidized at high temperatures and can only be used in neutral or reductive atmospheres, except for vacuum. Its Coefficient of thermal expansion is smaller, its thermal conductivity is higher, its resistance coefficient is (8 ~ *3) × ***6ω · m, its processability is better than SIC and Mosi2 bars, its high temperature resistance, extreme cold and extreme heat resistance is better, and its price is cheaper.
