The characteristics of coal pitch mainly include:

Source: Coal pitch is the residue left after the distillation of coal tar, with unique and diverse properties.

Physical Properties: Coal pitch is black in color with a certain gloss, high density, good heat resistance, and corrosion resistance. Additionally, coal pitch has certain viscosity and plasticity, making it widely applicable in construction and engineering fields.

The main uses of coal pitch include:

1. Electrode Manufacturing: Coal pitch can be used as a binder for electrode materials, such as graphite electrodes and carbon electrodes, improving mechanical strength and electrical conductivity.

2. Coatings: Coal pitch can serve as a main component in coatings for buildings, bridges, pipelines, etc., offering good adhesion, corrosion resistance, and weather resistance.

3. Chemical Industry: Coal pitch is also widely used in the chemical industry as a raw material for producing chemical products and for manufacturing carbon black.
