Description
Изобретение относитс к электровакуумной технике, в частлости к способам изготовлени фотокатода на основе теллурощелочных соединений.The invention relates to electrovacuum technology, in particular, to methods for producing a photocathode based on tellurium compounds.
Известен способ изготовлени фотокатода на основе теллурощелочных соединений путем испарени теллура из испарител , содержащего соединени теллура с индием.A known method of making a photocathode based on tellurian compounds by evaporation of tellurium from an evaporator containing tellurium compounds with indium.
Недостаток известного способа состоит в его сложности, так как соединени системы теллур-индий термически устойчивы и разлагаютс только п,ри 31начительНОм перегреве или же за счет перитектического превращени .The disadvantage of this method lies in its complexity, since the tellurium-indium system compounds are thermally stable and decompose only n, with significant overheating or due to peritectic transformation.
Предложенный способ изготовлени фотокатода состоит в том, что испарение теллура производ т из испарител , содержащего соединени теллура с тугоплавкими металлами. В качестве указанного соединени могут быть использованы теллурид вольфрама с содержанием вольфрама 42 вес. %, теллурид молибдена с содержанием молибдена 36 вес. %, теллурид рени с содержанием рени пор дка 42 вес. %.The proposed method for making a photocathode is that tellurium is evaporated from an evaporator containing tellurium compounds with refractory metals. As this compound, tungsten telluride with a tungsten content of 42 wt. %, molybdenum telluride with a molybdenum content of 36 wt. %, rhenium telluride with rhenium content of about 42 wt. %
Применение этих соединений в качестве распылител дл теллура позволит повысить температуру обезгаживани прибора до 400-450°С . Распыление теллура из этих соединений путем пр мого нагрева в вакууме, так же какThe use of these compounds as a spray for tellurium will increase the degassing temperature of the device to 400-450 ° C. Spraying tellurium from these compounds by direct heating in vacuum, as well as
и их получение, е вызывает технических затруднений .and obtaining them, does not cause technical difficulties.
Соединени теллура, используемые при изготовлении фотокатодов предложенным способом , - это термически неустойчивые соедпйени , темпе|ратура начала их разложени 600-800° С. При термическом разложении теллур полиостью удал етс из соединени , тугоплавкий же металл вследствие чрезвычайно низкой упругости пара остаетс .The tellurium compounds used in the manufacture of photocathodes by the proposed method are thermally unstable compounds, the temperature of their decomposition is 600-800 ° C. During thermal decomposition, tellurium is completely removed from the compound, and the refractory metal remains due to the extremely low elasticity of the vapor.
