| 專利摘要 | A preparation method of high purity and densified tungsten-titanium metal which mixes titanium metal powder and tungsten metal powder together; adds metallic nitrates (such as nickel nitrate) as combustion improvers; then taking into the account of the characteristics of metal nitrate, which is soluble in alcohols to form a liquidous precursor, adds metal powder to mix together thoroughly, so that the sintering agent is expected to be colloid and uniformly spread among the tungsten-titanium metal powder. The preparation method significantly reduces the ratio of the combustion improver during the preparation of the high purity and densified tungsten-titanium target material. |
