실험 절차
A strontium nitrate solution was prepared by dissolving 0.0302 grams of strontium nitrate in 50 milliliters of a mixture of 4 parts by volume of methanol and 1 part by volume of water. The solution was added to very finely-divided particles of silver to provide 0.025 percent strontium by weight of the mixture. The mixture and similar undoped particles of silver were pressed into compacts at 4 tons per square inch. The undoped compacts had a density of 5.28 grams/cc and the doped compacts had a density of 5.65 grams/cc. The compacts were heated to 650° C at 25° C/min and held at that temperature for 20 minutes. They were then heated to 875° C at 25° C/min and held at that temperature for 21/4 hours. The resulting undoped pieces had a density of 8.93 grams/cc and an electrical conductivity of 89 percent IACS. The doped pieces had a density of 9.55 grams/cc and an electrical conductivity of 97.5 percent IACS. Surface blistering was slight on the undoped pieces and very slight on the doped pieces.
