company news about Quality index judgment of metallic silicon powder

1, small ball formed coke, porous structure such as spongy, large small ball formed coke, dense structure such as fiber or needle, its quality is better than sponge coke. In the quality index, true density roughly represents this property, high true density indicates good crystallinity.

2, considering the powder coke and massive coke contained in the reaction coke, the relative content of available coke.

3, the content of sulfur and ash in oil coke. High sulfur coke will lead to products in the graphitization of gas swelling, resulting in cracks in carbon products. High ash content will hinder the crystallization of the structure and affect the service performance of carbon products.

4, coke products under the sudden rise to high temperature or from high temperature cooling of the thermal impact of the rupture resistance.
