Latest Patents

Nobuko Kasajima holds a patent for "Indium particle containing tin, method for producing the same and electroconductive sheet comprising the same." This invention involves a method where an aqueous solution of a tin salt and an indium salt is added to an aqueous alkaline solution. This process forms a hydroxide or hydrate comprising tin and indium, which is then heated at temperatures ranging from 110 to 300°C in the presence of water. After filtering and drying, the hydroxide or hydrate is further heated at temperatures between 200 to 1000°C to produce tin-containing indium oxide particles. These particles exhibit a plate-form shape and an average particle size in the plane direction of 10 to 200 nm, making them suitable for forming electrically conductive transparent coating films.
