Latest Patents

Kuwai's patent, titled "Process for production of composition," outlines a novel method for producing compositions that consist of perovskite structure compounds. The invention involves a two-step process: the first step requires heating a hydrous oxide of B group elements such as titanium, zirconium, hafnium, and tin within a temperature range of 80 to 300°C in the presence of an aqueous medium to dehydrate the hydrous oxide. The second step involves further heating the reaction product from the first step alongside hydroxides of A group elements such as barium, strontium, calcium, magnesium, and lead at temperatures between 100 to 300°C in an aqueous medium. This innovative process results in a uniform and fine spherical particle composition with an average diameter of 1 µm or less, specifically within the desirable range of 0.01 to 0.5 µm, characterized by high crystallinity and a controlled A/B ratio, along with minimal internal pores in the crystalline particles.
