Soft Carbon FAQs
Q1. How is Soft Carbon produced?
Soft carbon is typically produced by pyrolyzing organic precursors such as petroleum pitch, coal tar pitch, or synthetic polymers in the absence of oxygen. This process involves heating the material to high temperatures to remove non-carbon elements.
Q2. How should Soft Carbon be stored?
Store in a cool, dry place away from moisture and incompatible materials. Ensure containers are tightly sealed to prevent contamination.
Q3. Can Soft Carbon be customized for specific applications?
Yes, soft carbon can be tailored for specific applications by adjusting the pyrolysis conditions and precursor materials to modify its properties such as surface area, porosity, and electrical conductivity.
Q4. What is the difference between Soft Carbon and Hard Carbon?
Soft Carbon: Non-graphitizable with an amorphous structure, does not convert to graphite at high temperatures.
Hard Carbon: Also non-graphitizable but with a more ordered structure than soft carbon, used in applications requiring higher mechanical strength.
