(Wat is grafyt?)

Grafyt materiaal is benammen gearstald út polycrystalline grafyt, dat is in anorganysk net-metallysk materiaal, mar it hjit semy-metaal fanwege syn goede termyske en elektryske conductivity. Graphite has higher thermal and electrical conductivity than some metals, and at the same time It has a much lower coefficient of thermal expansion than metals, a high melting point and chemical stability, which makes it of important value in engineering applications. Graphite has good corrosion resistance and does not react with any organic compounds.

Graphite is also a high temperature resistant material. Graphite will not melt at high temperatures. Graphite also has good thermal shock resistance.

Graphite has good self-lubricating properties.

The disadvantage of graphite is that its resistance is poor, and as the temperature increases, the oxidation rate increases.

Gebrûk fan grafyt

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 steelmaking, graphite is often used as a protective agent for steel ingots and as the lining of metallurgical furnaces.

2. As a conductive material: used in the electrical industry to make electrodes, boarstels, carbon rods, carbon tubes, positive electrodes of mercury positive current devices, graphite washers, telephone parts, coatings for television picture tubes, ensfh.

3. As a wear-resistant lubricating material: Graphite is often used as a lubricant in the machinery industry.

4. Graphite has good chemical stability.

5. Graphite can be used as pencil lead, pigment and polishing agent

6. Graphite can replace copper as electrode
