With a total of 8 patents to his name, Kiyomoto's work has had a profound impact on both environmental safety and material science.
Latest Patents
One of Kiyomoto's latest patents is a method for the disposal of metallic aluminum-containing radioactive solid waste. This innovative method involves reacting radioactive solid waste containing metallic aluminum with an alkali solution to generate hydrogen gas. The resulting reaction liquid is then mixed with a solidifying material that contains a latent hydraulic material as its main component. This process allows for the solidification of aluminum-containing radioactive solid waste in a highly filled state, resulting in a solid with excellent mechanical strength and properties that prevent the oozing of radioactive nuclides.
Another significant patent is for a high-strength composite material and the process for producing it. This composite material is created by kneading a mixture of a non-hydraulic inorganic material, a water-soluble polymer, and water. The kneaded mixture is then molded and dried, with the option of treating the dried material with an isocyanate compound. This process results in a high-strength composite material that has various applications in different industries.
