鎢酸鹽陰極的研制
AN INVESTIGATION OF THE Ba Sr TUNGSTATE CATHODE FABRICATION METHODS

摘要: 正 鎢酸鹽陰極是一種壓制的補(bǔ)償式陰極。它是由鎢海綿內(nèi)含有均勻分布的作為活性物質(zhì)的鎢酸鋇鍶和作為還原劑的鋯組成的。 這種陰極是美國通用電氣公司首先研制成功,于1965年首次報(bào)道的。它具有發(fā)射電流密度大、工作溫度較低、工作溫度范圍寬、壽命長等優(yōu)點(diǎn)。該公司于1969年發(fā)表了他們的最后研制報(bào)告,隨后進(jìn)行過渡生產(chǎn),從1973年起,在研制成功這種陰極的Bondley直接指導(dǎo)下,進(jìn)行了兩年的工作才基本成功。在這過程中他們發(fā)現(xiàn)這種陰極工藝

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. -
