摘要： An electrochemical displacement-deposition method for making composite metal powders is described. The method is carried out by combining tungsten or molybdenum metal particles with particles of silver oxide or copper oxide in an aqueous hydroxide solution. Heat is applied to the solution to cause the oxide particles to convert to silver or copper metal particles which are substantially adhered to the refractory metal particles. Unlike conventional methods, it is not necessary to heat the oxide powders to a very high temperature in a reducing atmosphere in order to form the composite metal powder.
摘要翻译：描述了制备复合金属粉末的电化学位移沉积方法。该方法通过在氢氧化物水溶液中将钨或钼金属颗粒与氧化银或氧化铜的颗粒结合来进行。对溶液施加热量，使氧化物颗粒转化为基本上粘附到难熔金属颗粒上的银或铜金属颗粒。与常规方法不同，为了形成复合金属粉末，在还原气氛中不需要将氧化物粉末加热到非常高的温度。

摘要： A dispensable brazing paste useful in lamp manufacturing includes a brazing powder and a water soluble vehicle that has water, glycerin, a binder, and a dispersant that includes ammonium stearate and ammonium citrate. Preferably, the brazing powder is 84-87 wt % of the paste, the water is 3-5 wt %, the glycerin is 3-4 wt %, the binder is 1-2 wt %, and the dispersant is 4-6 wt %, and a weight of the water is within a range of 60-90% of a weight of the dispersant. The brazing paste does not include the troublesome organic solvents of the prior art.
