potassium hydroxide, oleylamine, or oleic acid. Single-phase powders of a variety of intermetallic compounds were synthesized. Although not stable at the temperature of synthesis, high-temperature phases are accessible as well. The microwave-assisted polyol process opens up the possibility to synthesize intermetallic compounds in a fast and easily applicable one-step route, without the utilization of
微波辅助多元醇工艺用于合成 TM 系统中金属间相的纯相微晶或纳米晶样品(T = Co、Ni、Rh、Pd、Ir、Pt 和 M = Sn、Sb、Pb、Bi )。反应温度范围在 240 °C 和 300 °C 之间,几分钟到一小时的反应时间就足够了。为优化合成反应温度、反应时间和金属前驱体。为了获得相纯样品,该过程通过添加氢氧化钾、油胺或油酸进一步改进。合成了多种金属间化合物的单相粉末。虽然在合成温度下不稳定,但也可以进入高温相。
