Title: Charles R. Doenitz: Inventor of a Monoclinic Titanium Dioxide Preparation Process
Introduction
Charles R. Doenitz is an inventor based in Plymouth, Michigan, United States. His work includes a patented process for preparing titanium dioxide with a monoclinic crystal structure. Doenitz is associated with Pacific Industrial Development Corporation.
Latest Patents
Doenitz is credited with 1 patent, titled “Preparation Process for Monoclinic Titanium Dioxide.” The invention describes a method for producing titanium dioxide by combining titanium and potassium precursors at a specified potassium-to-titanium molar ratio, then sintering the mixture at 750°C to 900°C. The resulting powder is soaked in an acidic solution, collected and dried, and thermally treated at 300°C to 500°C. The process produces titanium oxide whose major crystal phase is monoclinic TiO(B), accounting for more than 50% of the material’s total mass.
Career Highlights
The patent reflects Doenitz’s contribution to materials processing, particularly the preparation of titanium dioxide with a targeted crystal structure. The disclosed sequence of precursor mixing, sintering, acid treatment, and thermal processing provides a defined approach to producing the material.
Collaborations
Doenitz’s listed coworkers include Yuhao Liao and Bing Tan. His company affiliation is Pacific Industrial Development Corporation.
Conclusion
Charles R. Doenitz’s patent documents a process for preparing monoclinic titanium dioxide and highlights his work in materials innovation.
