Latest Patents

Yiyi Ma's latest patent focuses on the production of nickel composite particles. These particles feature a layer of a nickel-containing spinel on at least a part of the surface of nickel particles. Alternatively, they may have an oxide layer of metals other than nickel on at least a part of the surface of nickel particles, along with a nickel-containing spinel layer at the interface. The production process involves forming fine liquid droplets from a solution containing thermally decomposable nickel and metal compounds. These droplets are then heated to create nickel particles while simultaneously depositing a nickel-containing spinel layer or a metal oxide layer. This innovation is particularly useful for preparing conductor paste used in the internal conductor layer of ceramic multilayer electronic parts.
