た９、Ｍｏと化合物を作ること々く、Ｌａ２０．。[Technical Background of the Invention and Its Problems J Mo containing La20B is mainly used as a cathode phase material in electron tubes after being made into a wire or plate shape. etc., used by secondary processing,
Like ThO2 in tungsten containing thorium oxide (Th02-W), La2O3 in Mo often forms a compound with 9 and Mo dissolved in MO. .
の粒子として分散している。It is dispersed as particles.
このため、Ｍｏ中のＬａ２Ｏ３微粉の分散性が不良の場
合には、線せたは板状に加工する際、断線したり、割れ
たりするため加工が非常に困難であった。For this reason, if the dispersibility of the La2O3 fine powder in Mo is poor, it is very difficult to process the wire or plate because it may break or crack.
また、Ｍｏはもともと銅、アルミニウム等と比較し、非
常に脆い金属であり、コイル状にしたり、板全曲けたす
する等、二次加工をすることがむずかしい材料である。Moreover, Mo is originally a very brittle metal compared to copper, aluminum, etc., and is a material that is difficult to perform secondary processing, such as forming into a coil shape or completely bending a plate.

が最も一般的な方法である。In order to improve this secondary workability, the Mo sintered body or molten ingot is processed at a high processing rate (area reduction rate), and a fiber structure is developed in the processing direction (the transition temperature is set at room temperature). The most common method is to completely improve the flexibility of the wire or plate.

させることなく均一に分散埒せることが必要であった。The present inventors focused on the above-mentioned problems and determined that La2O3 is 1 to 1.
In order to facilitate secondary processing of MO containing MO, such as making the wire into a coil or bending a plate, the processing rate from the sintered body should be 60% or more. Through experimental research, we have found that it is necessary to have a processing rate of 60fo or higher.
It was necessary to uniformly disperse the fine La20° in the Mo powder, and for that purpose, it was necessary to uniformly disperse La2O3k in the Mo powder without agglomerating it.

ること番コ、いう賛でもない。As is clear from the above explanation, the method of the present invention includes: (1)
Since the addition of a203 is carried out in the form of a solution of La(NOs)3.6H20, it can be uniformly and finely dispersed in Mo. ■ Therefore, it can be easily processed into a wire or plate shape. Accordingly, the processing rate from the sintered body can be increased, and as a result, the secondary workability of the wire or upper plate is almost the same as that of pure MO. ■ La20 * can be uniformly dispersed in Mo, giving it great properties as a structural material.IFiJ
The industrial value of the above effects is extremely low1.The solution dispersion method according to the present invention can be applied to La(NOs).
Similar effects can be obtained by using other 6f-soluble compounds that generate La oxides by heating in place of 3.
It's not even a compliment.
