Advances in organoelement chemistry for the development of new materials

With the development of organoelement chemistry, polymer-to-ceramic technology based on the pyrolysis of organoelement ceramics-forming polymers (oligomers) acquires increasing interest. The organoelement ceramics-forming polymers are primarily organosilicon polymers (oligomers) – poly(oligo) carbosilanes and oligocarbosilanes modified by refractory metals (Zr, Hf and Ta), on whose pyrolysis carbide ceramics are formed. The use of polycarbosilanes and metal-containing carbosilanes in ceramics composite tech- nology makes it possible to obtain binary and more complicated carbide ceramics with the uniform distribution of the elements at the molecular level and with the controlled structure, which allows one to enhance the quality of the final material.
