High Expandable Rate 300 Graphite Powder FC 99
Graphite is an allotrope of carbon. It is a gray-black, opaque solid with stable chemical properties, corrosion resistance, and it is not easy to react with chemicals such as acids and alkali. It can be used as anti-wear agent and lubricant. High-purity graphite is used as a neutron moderator in atomic reactors. It can also be used to make crucibles, electrodes, brushes, dry batteries, graphite fibers, heat ex-changers, coolers, electric arc furnaces, arc lights, pencil refills, etc.

Applications
1: Used as refractory material: Graphite and its products have the properties of high temperature resistance and high strength. It is mainly used in the metallurgical industry to make graphite crucibles. In steel-making, graphite is often used as a protective agent for steel ingots and as a lining for metallurgical furnaces.
2:Used as conductive material: used in the electrical industry to make electrodes, brushes, carbon rods, carbon tubes, positive electrodes of mercury positive current devices, graphite washers, telephone parts and coatings for television picture tubes.
3: Used as wear-resistant lubricating material: Graphite is often used as a lubricant in the machinery industry. Lubricating oil often cannot be used under high-speed, high- temperature, and high-pressure conditions, while graphite wear-resistant materials can work at high sliding speeding at a temperature of 200-2000oC without lubricating oil. Many equipment that transports corrosive media widely use graphite materials to make piston cups, seals and bearing. They do not need to add lubricating oil during operation.
