20080317654 | Boron Suboxide Composite Material - A boron suboxide composite material having improved fracture toughness consists of particulate or granular boron suboxide distributed in a binder phrase, such as Al | 12-25-2008 |
20100300004 | BORON SUBOXIDE COMPOSITE MATERIALS - The invention provides a boron suboxide composite material comprising boron suboxide and a secondary phase, wherein the secondary phase contains a boride. The boride may be selected from the borides of transition metals of the fourth to eighth groups of the periodic table. Particularly, the boride may be selected from the borides of iron, cobalt, nickel, titanium, tungsten, hafnium, tantalum, zirconium, rhenium, molybdenum or chromium. The boride also may be a platinum group metal boride, preferably palladium boride. The secondary phase also may contain one or more oxides. | 12-02-2010 |
20100304138 | BORON SUBOXIDE COMPOSITE MATERIAL - The invention provides a boron suboxide composite material comprising boron suboxide and a secondary phase, wherein the secondary phase contains a mixture of at least two metal oxides, neither of which is a boron-containing oxide. At least one of the oxides may be selected from oxides of elements of Groups IA, IIA, IIIA, and IVA of the periodic table. Also, at least one of the oxides may be a rare earth metal oxide selected from the oxides of scandium, yttrium, and elements of the ianthanide series. The secondary phase of the composite material may also contain a boride, and particularly a boride selected from the borides of transition metals of the fourth to eighth groups of the periodic table. | 12-02-2010 |
20100308256 | BORON SUBOXIDE COMPOSITE MATERIAL - The invention provides a boron suboxide composite material comprising boron suboxide and a secondary phase, wherein the secondary phase contains a rare earth metal oxide. The rare earth metal oxide may be selected from the oxides of scandium, yttrium, which is preferred, and elements of the lanthanide series, and may be a mixture of rare earth metal oxides. The secondary phase may also include, in addition to the rare earth metal oxide(s), a further oxide or mixture of oxides of an element of the Groups IA, MA, MIA, and IVA of the periodic table. Moreover, the secondary phase may also contain a boride, and particularly a boride selected from the borides of transition metals of the fourth to eighth groups of the periodic table. | 12-09-2010 |
