PRODUCTION OF HIGH-PURITY TITANIUM MONOXIDE AND CAPACITOR PRODUCTION THEREFROM

摘要

The present invention relates to high-purity titanium monoxide powder (TiO) produced by a process of combining a mixture of titanium suboxides and titanium metal powder or granules; heating and reacting the compacted mixture under controlled atmosphere to achieve temperatures greater than about 1885° C, at which temperature the TiO is liquid; solidifying the liquid TiO to form a body of material; and fragmenting the body to form TiO particles suitable for application as e.g., capacitors. Alternatively, the present invention relates to high-purity titanium monoxide powder (TiO) produced by a process of combining a mixture of titanium suboxides and titanium metal powder or granules; reacting the mixture at a temperature above about 1200°C; and fragmenting the body to form TiO particles suitable for capacitors. The TiO product is unusually pure in composition and crystallography, highly dense, and can be used for capacitors and for other electronic applications. The method of production of the TiO is robust, does not require high-purity feedstock, and can reclaim value from waste streams associated with the processing of TiO electronic components.
