Latest Patents

One of Jinshu Wang's latest patents is a method for preparing pressed scandia-doped dispenser cathodes using microwave sintering. This method involves dissolving certain nitrates and ammonium metatungstate in deionized water to create a homogeneous solution. The precursor powder is obtained through spray drying, followed by decomposition and a two-step reduction process to form doped tungsten powder with uniform element distribution. The cathode is then prepared through one-time microwave sintering, which significantly reduces sintering shrinkage and time while ensuring excellent repeatability and emission performance at 950°C. Another notable patent is the carburized LaO and LuO co-doped Mo filament cathode. This cathode is made from lanthanum oxide and lutetium oxide doped molybdenum powders, with a total concentration of LaO and LuO ranging from 2.0 to 5.0 wt.%, while the remainder consists of Mo.
