Manufacturing method for oxide cathode
专利汇可以提供Manufacturing method for oxide cathode专利检索，专利查询，专利分析的服务。并且PURPOSE:To stabilize the efficiency of thermal radiation and make durable against electric sparks by coating a suspension of an alkaline earth carbonate containing nickel oxalate on a cathode substrate and, after decomposing the nickel oxalate by heating, incorporating said cathode substrate in an electron tube. CONSTITUTION:Nickel nitrate is caused to react with oxalic acid toform nickel oxalate, which is dispersed into an organic solvent in an atmosphere of an inert gas. The organic solvent containing this undercomposed nickel oxalate powder is mixed with an alkaline earth carbonate to form a suspension. In the next place, after coating of the resultant suspension on a cathode substrate, it is heat-treated in an atmosphere of a nonoxiding gas and thereby the nickel oxalate is decomposed. Finally the cathode is enclosed in an electron tube. An heat treatment of the cathode during the evacuation of the tube changes the alkaline earth carbonate to its corresponding oxide.，下面是Manufacturing method for oxide cathode专利的具体信息内容。
