钨酸盐阴极的研制
AN INVESTIGATION OF THE Ba Sr TUNGSTATE CATHODE FABRICATION METHODS

摘要: 正 钨酸盐阴极是一种压制的补偿式阴极。它是由钨海绵内含有均匀分布的作为活性物质的钨酸钡锶和作为还原剂的锆组成的。 这种阴极是美国通用电气公司首先研制成功,于1965年首次报道的。它具有发射电流密度大、工作温度较低、工作温度范围宽、寿命长等优点。该公司于1969年发表了他们的最后研制报告,随后进行过渡生产,从1973年起,在研制成功这种阴极的Bondley直接指导下,进行了两年的工作才基本成功。在这过程中他们发现这种阴极工艺

Abstract: An investigation of the Ba Sr Tungstate cathode was made. It was found that when the tungstate was prepared at 1050℃ for 2 hours the product was stable in the atmosphere, and storing in air with relative humidity of below 70% for 200 hours, its increase in weight was only 0.2%. Cathodes made this way have a reasonably long life. -
