Phenolformaldehyde resins (PFRs) were modified with silicon alkoxide and transformed during heating. The physicochemical processes occurring as the PFRs were heated were established. The oxidation-resistance of PFRs modified by silicon alkoxide increased upon heating. Low-temperature synthesis of SiC from them was confirmed.
