Abstract

본 발명은 상,하판으로 된 고정대로서 다공질 텅스텐 펠렛에 전자 방사물질을 함침시 다량의 펠렛을 얻을 수 있도록 대량 생산할수 있고, 고가의 전자 방사물질이 손실되는 것을 최소화하여 제작 단가를 절감시킬 수 있는 등의 많은 장점이 구비된 것이다.The present invention relates to a method of manufacturing a porous tungsten pellet in which a porous tungsten pellet is impregnated with an electron-emitting material to produce a large amount of pellets when impregnated with the electron-emitting material, and the loss of expensive electron- And so on.

이를 위해, 본 발명은 전자 방사물질을 함침하기 위해 고융점 금속으로 된 고정대(1)의 상판(2)에 다공질 텅스텐 펠렛(3)과 전자 방사물질(4)이 안착되도록 하기 위한 복수개의 통공(5)이 형성되고, 상기 상판(2)과 하판(6)에는 상,하판(2)(6)을 체결하기 위한 고정공(8)(9)이 형성되어 결합된 전자 방사물질 함침용 고정대이다.To this end, the present invention is characterized in that a porous tungsten pellet (3) and an electron emitting material (4) are seated on an upper plate (2) of a fixing table (1) 5 are formed on the upper and lower plates 2 and 6 and fixing holes 8 and 9 for fastening the upper and lower plates 2 and 6 are formed on the upper and lower plates 2 and 6, .
