Special features of natural flake graphite

Flake graphite is a natural non-metallic mineral resource. After mechanical crushing, flake graphite can be processed into natural flake graphite powder of different specifications and meshes. Natural flake graphite powder has good lubricating properties, electrical conductivity, high temperature resistance, etc. Natural flake graphite powder for conduction is used in the field of conductive material production.

Advantages of flake graphite

1. The application loss of natural flake graphite on the electrode is low, thus avoiding the number of repeated electrode processing. The chemical properties of graphite are stable and non-toxic. It begins to oxidize at 400°C, and it can react with water vapor above 700°C, and it can react with water vapor at 900°C The above can react with CO2, and only react with hydrogen when it is above 1000. It can resist the erosion of various acids, alkalis and organic solvents.

2. Natural flake graphite can react with many metals or non-metals or their oxides at high temperature. It has the characteristics of coatability, light weight, high plasticity, and easy processing. It is also an important carbon source that can provide various Higher purity carbon required in this material.

3. Natural flake graphite powder can stabilize the voltage of the lithium battery, reduce the internal resistance of the lithium battery, make the storage time of the battery longer, and increase the utilization time of the battery.

4. Natural flake graphite powder has many advantages such as high electronic conductivity, large lithium ion diffusion coefficient, high embedding capacity and low embedding potential, so flake graphite powder is one of the most important materials for lithium batteries.

Application of flake graphite

1. Natural flake graphite is soft, with a hardness of 1-2, and its hardness can increase to 3-5 along the vertical direction with the addition of impurities, and its specific gravity is 1.9-2.3. Under the condition of being separated from oxygen, its melting point is above 3000 ° C, which is relatively durable. One of the warmest minerals. Natural flake graphite has been developed as a lubricating additive for a long time. Graphite powder is used in vehicle engines with a good fuel saving rate of about 10%. Expanded graphite is a kind of loose and porous natural flake graphite obtained by intercalation, washing, drying and high temperature expansion. The worm-like graphite has good compatibility with oil medium.

2. Baking pans and pots made of natural graphite flakes heat up quickly, and the cooked food is heated evenly, cooked from the inside out, and the heating time is short. Not only the taste is pure, but also the nutrients of the food itself can be locked. When the natural flake graphite grill pan is grilling meat, the electric speed furnace can be preheated in only 20-30 seconds when it is turned on to a high fire at the beginning, and it can be preheated in only 20-30 seconds.

3. Natural flake graphite has good chemical stability at room temperature, and is not affected by any strong acid, strong sensitivity and organic solvent. Therefore, even if the stone product is used for a long time with little source, as long as it is wiped clean, it will still look like new.
