<p>Burning-on alloy comprises (wt.%) cobalt (55-65), chromium (20-30), tungsten and/or molybdenum (the sum of the content by weight of molybdenum and half the content by weight of tungsten is 4-12), gallium (2-4), silicon (0-2), manganese (0.05-1.9), nitrogen (0-0.4), carbon (0-0.2); vanadium, niobium, tantalum, iron, titanium, zirconium, hafnium (in total 0-5); nickel (0-0.1); platinum group metals, rhenium, gold, silver, and copper (in total 0-0.09); and other metals, semi-metals, and impurities (0-1). An independent claim is also included for ceramically veneered dental restoration, comprising a dental structure of the inventive alloy, and a dental ceramic burned on to the dental structure having a Thermal Expansion Coefficient of 13x10 -6>/[deg]K to 15x10 -6>/[deg]K.</p> |
