Publication number: 20150322268Abstract: Powders such as pigmentary titanium dioxide (TiO2) often demonstrate poor bulk handling properties. It is very cohesive, often dusty, and many grades have loose bulk densities that are lower than desired by customers for their processes. The present invention relates to a process for manufacturing low-dusting, smoothly-discharging, easily dispersible, powders such as pigmentary titanium dioxide that resist compaction, aging, lumping, and/or caking. Particularly, the present invention relates to a process for treating powders such as pigmentary titanium dioxide with ammonia or a similarly basic substance prior to or during agglomeration to produce a powder with improved bulk handling properties. The present invention also relates to powders treated as such, including titanium dioxide.Type: ApplicationFiled: March 29, 2013Publication date: November 12, 2015Applicant: E I DU PONT DE NEMOURS AND COMPANYInventors: TIMOTHY ALLAN BELL, DAVID RICHARD CORBIN, SCOTT HUTCHISON, EUGENE MICHAEL MCCARRON, III, THOMAS C.

Patent number: 7628937Abstract: The present invention relates to processes for making anodes suitable for use in the production of titanium metals. The processes use a kneaded mixture of TiO2 particles, carbon particles, a binder, and a solvent. The mixture is extruded and the solvent is allowed to evaporate to form a green body which is subsequently fired. During firing of the green body, the carbon particles aid in reducing the titanium dioxide to a lower oxide or oxycarbide which can be electrochemically processed into titanium metal.Type: GrantFiled: December 17, 2007Date of Patent: December 8, 2009Assignee: E.I. du Pont de Nemours and CompanyInventors: Eugene Michael McCarron, Dennis A.

Patent number: 6498046Abstract: An infrared thermographic technique for rapid parallel screening of compositional arrays of potential chemical sensor materials has been developed. The technique involves applying a voltage bias and the associated current to the sample array during screening. The thermographic response is amplified by the resistance change that occurs with gas adsorption, and is directly monitored as the temperature change associated with I2R heating. This technique can also be used to determine n- or p-type character for the semiconductor in question.Type: GrantFiled: October 16, 2001Date of Patent: December 24, 2002Assignee: E.
