Modification of Ceramic by Organosilicon Polymer Capable of Transitioning Into Silicon Carbide

详细

The possibility of increasing the strength of ceramic by introducing the ceramic-forming polymer polydimethylsilane into the batch is examined. Upon the introduction of polydimethylsilane into the mix a transition of polydimethylsilane into polycarbosilane is observed in the presence of the catalyst molybdenum chloride and is followed by a transition of polycarbosilane into silicon carbide. It is shown that the introduction of this additive with weight content > 4% increases strength and decreases open porosity.
