Opportunities for Enhancing the Thermal Conductivity of SiC and Si3N4 Ceramics Through Improved Processing Chapter in Ceramic Engineering and Science Proceedings 16(4) - · . This is the final technical report for the program entitled "Improved Silicon Carbide for Advanced Heat Engines" and includes the work performed during the period February 12, to DecemberIi, The program was conducted for the National Aeronautics and SpaceAdministration (NASA) under contract numberNAS This work presents the results of studies on the thermal and electrical properties of sintered silicon nitride to investigate the effects of non-oxide additives. With regard to electrical transport properties, a high electrical resistivity of 10 14 ∼ 10 15 Ωcm at K was observed with Si 3 N 4 by: 5. Aug 29,  · The purpose of joining, Phase 2 was to develop joining technologies for HIP`ed Si{sub 3}N{sub 4} with 4wt% Y{sub 2}O{sub 3} (NCX) and for a siliconized SiC (NT) for various geometries including: butt joins, curved joins and shaft to disk joins. In addition, more extensive mechanical characterization of silicon nitride joins to enhance the predictive capabilities of the Cited by: 6.
