Hvað er grafít?

(Hvað er grafít?)

Grafít efni er aðallega samsett úr fjölkristölluðu grafíti, sem er ólífrænt málmlaust efni, en það er kallað hálfmálmur vegna góðrar hita- og rafleiðni. 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.

Notkun grafíts

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. Sem leiðandi efni: used in the electrical industry to make electrodes, bursta, kolefnisstangir, kolefnisrör, positive electrodes of mercury positive current devices, grafít þvottavélar, símahlutar, húðun fyrir sjónvarpsmyndrör, o.s.frv.

3. As a wear-resistant lubricating material: Grafít er oft notað sem smurefni í vélaiðnaði.

4. Grafít hefur góðan efnafræðilegan stöðugleika.

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

6. Graphite can replace copper as electrode
