Reduction of metal oxide to metal in powder form is used in the manufacture of high melting metals such as tungsten, titanium etc. High melting alloys are made by compressing powders of the metals. This is followed by sintering in an electric furnace. The sintering temperature of a powder is usually at about 􀒀th of the melting point of the metal. Thus powder metallurgy technique lower the temperature necessary for making high melting alloys and this is an important advantage of powder metallurgy. (Because the melting point of powder mixture is lower than the melting point of pure metal). It can also be used in the manufacture of ferrous metals.
