CarboSiC™10
Polycarbosilane Preceramic Polymer
CarboSiC 10 is a SiC forming preceramic precursor used for the fabrication of high temperature resistant composite materials. CarboSiC 10 is thermally converted to an amorphous SiC state between 825⁰C to 1225⁰C with a ceramic yield between 70% and 75%, and converted to a crystalline ceramic state between 1250⁰C and 1725⁰C.
Due to the level of polymer purity, a near 1:1 stoichiometric silicon to carbon yield is achieved. As a result, the converted material remains stable in atmospheric service temperatures up to 1800+⁰C.
CarboSiC 10 produces a superior capability to maintain critical structural integrity and mechanical properties at temperatures higher than any other commercially available SiC producing material. This stability is primarily due to the superior covalent bonding between silicon and carbon atoms in the SiC structure. CarboSiC 10 converted SiC ceramics exhibit low thermal expansion and high thermal conductivity, essential for managing intense heat fluxes.

V-PSZ™20
Preceramic Organic Polysilazane for Si3N4 and SiCN
V-PSZ™20 is an ammonolysis synthesized low odor poly(vinyl)silazane ceramic precursor designed to remain stable at temperatures in excess of 1300°C, and when properly modified, in excess of 1600°C in oxidizing environments.
This stability is primarily due to the superior covalent bonding between silicon and nitrogen atoms in the Si-N structure. V-PSZ™20 thermally converted Si3N4 ceramics exhibit low thermal expansion and high thermal stability, essential for managing high heat fluxes.
V-PSZ-20 is used for fabrication of complex ceramic matrix composite shapes with excellent thermal, chemical, and mechanical properties, including density, hardness, and corrosion resistance.

Polysilazane is a highly versatile material used in many advanced applications beyond ceramic matrix composites (CMCs), particularly where high thermal and chemical stability are required. Contact CermeTech for more information.
