Abstract

Coking of phenolformaldehyde resins (PFRs) modified with various silicon-alkoxide sols produced structurally varied carbon binders with cavities filled by entrained sols, depending on the structures of the silicon-alkoxide hydrolysis products. The physicomechanical properties improved if PFRs modified with silicon-alkoxide sols were used. Sols with the stoichiometric amount of water hydrolyzed the silicon alkoxide more effectively.
