Latest Patents
Nomura's recent patents include groundbreaking methods for producing sintered silicon carbide articles. The first patent focuses on a method for producing a sintered silicon carbide article that achieves a sintered density of at least 90% of its theoretical density and a mechanical flexural strength of 50 kg/mm² or higher. This process involves adding a tar pitch to finely divided α-type silicon carbide powder, which, after carbonization, provides 4.2-6 parts by weight of carbon. Additionally, a boron compound is used as a densification aid, corresponding to a boron content of 0.005-0.15 parts by weight. The resulting mixture is then shaped and sintered in an inert atmosphere at temperatures ranging from 1950°C to 2300°C.
The second patent elaborates on a method for manufacturing high-strength sintered silicon carbide articles. This innovation pertains specifically to achieving high mechanical strength by mixing finely divided silicon carbide powder with precise amounts of a carbon-containing material, a boron compound, and silicon powder as densification aids. The subsequent shaping and sintering take place under an inert atmosphere, further enhancing the material's properties.
