摘要： An improved process for successful and homogeneous incorporation of ruthenium and iridium into titanium and titanium alloy melts, ingots, and castings via traditional melting processes (e.g., VAR and cold-hearth) has been developed. This result is achieved through the use of low-melting point Ti-Ru or Ti-Ir binary master alloys within the general composition range of null45 wt. % Ru and with a preferred composition of Ti-(15-40 wt. % Ru), or within the general composition range of null61 wt. % Ir and with a preferred composition of TI-(20-58 wt. % Ir). Primary features are its lower melting point than pure titanium, lower density than pure Ru and Ir metals, and the ability to be readily processed into granular or powder forms.

摘要： A titanium dioxide compound was isolated from a rare type of naturally occurring ore. Processes for efficiently isolating and obtaining these TiO2 compounds, as well as methods for using them have been developed. These TiO2 compounds may be used directly in applications such as paper, plastics and paints without being subjected to the chloride or sulfate processes. Also they made be used as a feedstock for the chloride or sulfate processes. In order to obtain these TiO2 compounds, one may grind or pulverize the naturally occurring ore, disperse it in a solution or suspension, and process it by selective flocculation or aqueous biphasic extraction.
