Latest Patents
Voigt's latest patents focus on tantalum (V) nitride pigments and their production processes. One of his inventions relates to tantalum (V) nitride pigments with improved color values compared to previously disclosed products. This process allows for the production of pigments with an a* color value in the CIE Lab system of equal to or greater than 45, and preferably equal to or greater than 50. The after-treatment of tantalum (V) nitride is conducted in a salt melt at temperatures ranging from 100 to 600 °C, specifically between 300 to 500 °C, for a duration of 1 to 100 minutes. These pigments can be utilized to color various materials, including plastics, paints, enamel, glass, and porcelain decorations.
Another patent involves the nitriding of tantalum (V) oxide with ammonia at temperatures between 700 to 1250 °C to yield tantalum (V) nitride. This process improves pigment quality by adding at least one pulverulent oxide, such as SiO2, GeO2, SnO2, TiO2, ZrO2, or HfO2, in a quantity of at least 0.1 wt. %, calculated as oxide, to the tantalum (V) oxide before nitriding.
