Latest Patents

One of Takeda's latest patents is a process for producing silicon carbide fibers. This invention provides a method for creating fibers with a C/Si molar ratio ranging from 0.85 to 1.39, which is superior to conventional processes that cannot achieve a ratio lower than 1.56. The process involves rendering infusible precursory fibers made from an organosilicon polymer compound, primarily baking these fibers in a hydrogen gas-containing atmosphere, and then subjecting them to a secondary baking process in a mixed gas atmosphere at temperatures between 1,500°C to 2,200°C.

Another notable patent is for a super heat-resistant silicon carbide fiber that contains less than 0.1% by weight of oxygen. This fiber is produced by irradiating a precursor fiber made from polycarbosilane with radiation in an oxygen-free atmosphere, making it infusible. The infusibilized fiber is then fired in an oxygen-free environment at temperatures ranging from 1,000°C to 2,200°C, ensuring it remains free from oxidizing conditions.
