Latest Patents

One of his latest patents is titled "Process for preparing crystalline barium titanate powder." This invention provides a method for preparing barium titanate powders that exhibit fine particle morphology and superior crystallinity. The process involves creating a sol precursor using a titanium acylate and a barium compound, followed by spraying the sol precursor in a strong alkaline solution for coprecipitation. The barium titanate is then crystallized, optionally using a hydrothermal reaction, and purified through washing.

Another significant patent is "Preparation of boron-doped silicon carbide fibers." This method outlines the preparation of polymer-derived silicon fibers. The process includes providing a spin dope solution that consists of a silicon carbide forming organosilicon polymer, a solvent, a soluble boron precursor, and a nitrogen-containing precursor. The solution is spun to create high-strength green fibers, which are then heat-treated to produce boron-doped silicon carbide fibers with impressive tensile strength ranging from about 2.0 to 4.0 GPa at room temperature.
