Latest Patents

Yang's latest patents include innovative methods for producing carbide cermet powders. The first patent describes a method for synthesizing nanostructured carbide cermet powders through high energy ball milling. This process involves milling a mixture of precursor powders and a carbon source, followed by annealing the milled powder mixture. The precursor powders are selected from materials suitable for cermet formation, including silicon, titanium, thorium, hafnium, vanadium, chromium, tungsten, tantalum, niobium, and zirconium-containing materials. The resulting tungsten cobalt carbide powders are submicron-sized, ranging from 0.2 to 0.4 microns, with internal nanograins measuring 10 to 40 nanometers in diameter.

The second patent focuses on synthesizing micron- and submicron-sized, nanostructured metal carbide powders. This method involves high energy milling of metal oxide and carbon precursors, followed by annealing the as-milled powders. The annealing process is preferably conducted under a flow of inert gas or subatmospheric pressure to ensure the reaction is completed within one to two hours. The synthesized powders exhibit high purity and a narrow particle size range.
