Latest Patents
One of Ueda's latest patents is a continuous process for preparing sodium percarbonate. This innovative method involves the continuous crystallization of sodium percarbonate through a series of reaction vessels. The process includes several steps, such as continuously feeding sodium carbonate and hydrogen peroxide into the first reaction vessel, forming a slurry with seed crystals. The slurry is then transferred to a second vessel where final sodium percarbonate crystals are grown. This method ensures that the particle size of the final product does not exceed 100 µm, resulting in strong sodium percarbonate granules.
Another significant patent by Ueda is related to a powder composition for sintering into modified barium titanate. This invention aims to produce a semiconductive ceramic with high breakdown voltage and low specific resistance at room temperature. The composition includes a mixture of various titanium oxides and dopants, which are carefully balanced to achieve the desired electrical properties. The resulting ceramic is compacted and sintered at high temperatures, showcasing Ueda's expertise in material science.
