Flake graphite is a natural crystalline graphite that resembles fish scales and belongs to the hexagonal crystal system with a layered structure. Therefore, it still has good properties such as high temperature resistance, conductivity, thermal conductivity, lubrication, plasticity, and acid and alkali resistance. Below are some precautions for using flake graphite?

Flake graphite is a widely used product in the metallurgical industry for refractory materials and coatings. Such as magnesia carbon bricks, crucibles, etc. Now used as anti-corrosion material. Flake graphite is an anti rust primer made of carbon black, talc powder, and oil, which has good resistance to chemicals and solvents. If chemical pigments such as zinc yellow are added to the formula, its rust prevention effect will be better. When used, it has strong thermal shock resistance and good corrosion resistance, and is the main carbon raw material used in conjunction with refractory materials. It has a significant impact on the erosion resistance and high-temperature strength of carbon bonded refractory materials such as magnesia carbon bricks. In the actual production process, carbon bonded refractory materials have strict requirements for the purity, ash content, particle size, shape, and addition amount of flake graphite. The structure and function of graphite flakes after high-temperature firing largely depend on the wettability of high-temperature silicate liquids. When wet, the silicate liquid phase flows into the particle gaps under the action of capillary force. The flake graphite particles combine together through their adhesive force, forming a thin film around the flake shape. After cooling, they form a continuum and form a higher bonding interface with it.

The surface tension of flake graphite is low, with a large area without defects, and there is about 0.45% volatile organic compounds on the surface, which reduces the wettability of graphite. The strong hydrophobicity of the flake graphite surface reduces the fluidity of the castable. However, it is prone to aggregation and cannot be uniformly dispersed in refractory materials, making it difficult to prepare uniform and fine amorphous refractory materials. If both are not wet, flake graphite particles will form aggregates. The silicate liquid phase is confined within the particle gaps to form isolated bodies, making it difficult to sinter and form fine complexes at high temperatures. Alternatively, under heating, the volume rapidly expands (up to 300 times), suffocating the flame and producing expanding substances that can isolate the flame, delay or interrupt its spread. It is non combustible, has good flexibility, high surface energy, and a strong carbonization layer.
