Title: The Innovations of Robert A Johns
Introduction
Robert A Johns is a notable inventor based in Kennett Square, Pennsylvania. He has made significant contributions to the field of materials science, particularly in the production of titanium dioxide pigments. With a total of two patents to his name, his work has implications for various industrial applications.
Latest Patents
Johns' latest patents focus on processes for controlling particle size and silica coverage in the preparation of titanium dioxide. The first patent describes a vapor phase process for producing a substantially anatase-free titanium dioxide pigment. This involves reacting a vaporous titanium dioxide precursor with an oxygen-containing gas in a reactor. A mixture of liquid silicon halide and liquid titanium dioxide precursor is introduced into the reactor at a temperature range of about 1200°C to about 1600°C. This process results in titanium dioxide particles that are substantially encapsulated in silicon dioxide.
The second patent also addresses the control of particle size and additive coverage in titanium dioxide preparation. It similarly involves a vapor phase process, where a mixture of liquid titanium dioxide precursor and a finely divided solid compound is introduced into the reactor. This process also operates at a temperature range of about 1200°C to about 1600°C, producing titanium dioxide particles coated by the oxide formed from the selected elements.
