گرافیت چیست؟

(گرافیت چیست؟)

مواد گرافیت عمدتا از گرافیت پلی کریستالی تشکیل شده است, که یک ماده غیر آلی غیر فلزی است, اما به دلیل هدایت حرارتی و الکتریکی خوب آن را نیمه فلزی می نامند. 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.

موارد استفاده از گرافیت

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, برس ها, carbon rods, carbon tubes, positive electrodes of mercury positive current devices, graphite washers, telephone parts, coatings for television picture tubes, و غیره.

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
