What is the CAS number of carbon black?
The CAS of carbon black is [1333-86-4].

What is the pH of carbon black?
The pH of carbon black refers to the amount of chemisorbed oxygen present on the surface. For most grades, low concentrations of oxygen compounds and very few water-soluble salts on furnace carbon blacks neutralize slightly alkaline pH values. To enhance specific properties, several grades of carbon black have been surface oxidized to increase the number of chemisorbed oxygen groups present. These products therefore have an acidic pH (2 to 4).

What does dispersibility of carbon black mean?
The dispersibility of rhenium carbon black generally refers to its easy or difficult dispersibility. Usually this is a relative measure for standard carbon black grades. As carbon black-grade surface area decreases and / or structure increases, the carbon black's easy dispersibility increases. However, it should be noted that other properties of carbon black, such as color, will vary with these changes in surface area and structure.

What is the solubility of carbon black?
Carbon black is insoluble in water and solvents.
