Oxidation-Resistant Nano-Reinforced PC-refractories of Modified Phenolformaldehyde Resin. Part 1. Modification of Phenolformaldehyde Resins with Silicon Alkoxides

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 Si...

Description
Summary: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.
