Latest Patents

One of his latest patents is a method of decorating a ceramic article. This invention provides a technique that includes preparing an ink composition with a metallic soap, which is a viscous oil or waxy solid at about 25°C. The process involves heating the ink composition to reduce its viscosity, depositing micro-droplets of the heated ink on the ceramic article, and firing it in an oxidizing atmosphere. Notably, the ink composition is substantially solvent-free in the preferred embodiment.

Another significant patent is for a process of making bismuth-vanadium-molybdenum-containing compositions. This invention outlines a method that includes preparing three separate aqueous compositions with varying pH levels, combining them to form a fourth aqueous composition, and maintaining it at a specific temperature for a set duration. The process culminates in heating the precipitated solids to create the desired bismuth-vanadium-molybdenum-containing composition.
