Title: Innovations of John D. Pietras
Introduction
John D. Pietras is a notable inventor based in Alfred Station, NY (US). He has made significant contributions to the field of materials science, particularly in the production of ultra-fine particles. With a total of three patents to his name, his work has implications for various technological applications.
Latest Patents
One of his latest patents is titled "Process for making ultra-fine barium hexaferrite particles." This process involves several steps, starting with the provision of a ceramic precursor material containing barium and trivalent ferric cations, a nitrogen-containing material, a solvent, and an anion capable of participating in an anionic oxidation-reduction reaction. The second step involves forming droplets of this ceramic precursor material. In the third step, the droplets are dried until particles containing less than about 15 weight percent of solvent are produced. Finally, the particles are ignited in an atmosphere with substantially less than about 60 weight percent of the solvent's saturation value.
Another significant patent is "Process for making ultra-fine yttrium-iron-garnet particles." Similar to the previous process, it begins with a ceramic precursor material containing yttrium and ferric cations, along with a nitrogen-containing material, a solvent, and an appropriate anion. The subsequent steps mirror those of the barium hexaferrite process, leading to the production of ultra-fine yttrium-iron-garnet particles.
