Precursor material for carbon artifact manufacture |
(57) A precursor material for carbon artifact manufacture comprises pitch components blended
to give a ratio by weight of oxidisableto non-oxidisable products in the range 2.3
to 5.0 : 1. A precursor can be manufactured by blending extracted components of at
least one pitch to give an optimized mixture having the proper chemistries and rheology
to provide high strength carbon artifacts.
