随着以氧化铜为基础的高临界温度超导陶瓷的发现,进行了大量的研究工作,主要集中在这些材料独特的物理特性、结构特性以及理论模型的发展上。合成这些化合物的替换过程的进展不太引人注意。最近发现,几种无机氧化物包括 CuO,很强地吸收2450兆赫的微波辐射,这是一种用于家庭微波炉的频率。由于这种强吸收,1—5克的 CuO 样品达到的温度在1分钟暴露之后超过550℃,市场上可买到的微波炉在功率水平为500瓦下工作。我们采用合成混合金属氧化物的这种微波炉,包括具有超导特性的那种炉。
With the discovery of copper oxide-based high-temperature superconducting ceramics, a great deal of work has been done, focusing mainly on the unique physical, structural properties and theoretical models of these materials. The progress of the replacement process for the synthesis of these compounds is less noticeable. It has recently been discovered that several inorganic oxides, including CuO, strongly absorb 2450 MHz microwave radiation, a frequency used in domestic microwave ovens. Due to this strong absorption, temperatures of 1 to 5 grams of CuO sample reached over 550 ° C after 1 minute exposure and commercially available microwaves operated at a power level of 500 watts. We use such microwave ovens that synthesize mixed metal oxides, including those with superconducting properties.
