 Fixed carbon is not available as such, for example, CO2 from the air becomes fixed in plants and is thus removed from availability. 

Alternatively, you can have fixed carbon in eg coal. Fixed carbon is the solid combustible residue that remains after a coal particle is heated and the volatile matter is expelled. The fixed carbon content of a coal is determined by subtracting the percentages of moisture, volatile matter, and ash from a sample.
