With a total of 9 patents to his name, Kobayashi's work has had a lasting impact on various industrial applications.

Latest Patents

One of his latest patents is for a pressureless sintered body of boron nitride. This innovative material contains more than 95 wt% of boron nitride and boasts a density of not less than 1.10 g/cm³, along with a bending strength of not less than 300 kg/cm². The process for producing this pressureless sintered body involves pulverizing boron nitride powders to achieve a specific surface area that is at least twice that of the starting material. The pre-molded body is then sintered at a temperature of not less than 1400°C under atmospheric pressure and in a non-oxidative atmosphere.

Another notable patent is for a process for producing high-strength β-sialon-silicon carbide. This process includes mixing silicon nitride and silicon carbide with an aluminum alkoxide solution or a soluble aluminum salt solution. The resulting homogeneous mixture serves as a starting material for forming a sintered body. This method effectively eliminates defects such as pores and unsintered parts, thereby improving the strength of the final product.
