Abstract

Twenty-nine brands of dental casting nickel-chromium alloys made in Japan for small castings were analyzed by electron probe X-ray microanalyzer. Nickel-chromium alloys for metal-ceramic application were composed primarily of nickel, chromium, and molybdenum with the exception of one brand. Of the nickel-chromium alloys for inlay, crown, and bridgework applications, 11 of the 22 alloys were up to the standard of the Ministry of Welfare specifications. And additive metal elements of these alloys were molybdenum, iron, copper, manganese, aluminum, silicon, tin, indium, silver, titanium, and gallium.

镍铬牙科铸造合金的定量化学分析。
采用电子探针x射线微量分析仪对日本29个牌号的小型铸造用牙用镍铬合金进行了分析。金属陶瓷用镍铬合金主要由镍、铬和钼组成,只有一个牌号例外。在镶嵌、牙冠、桥架用镍铬合金中,22种合金中有11种符合厚生劳动省标准。这些合金的附加金属元素是钼、铁、铜、锰、铝、硅、锡、铟、银、钛和镓。
