Abstract

Patente de Invenção: <B>"ELETRODO FRIO PARA DESCARGAS DE GáS"<D>. A invenção refere-se a eletrodos frios para descargas de gás, com um material de suporte (1) que conduz eletricidade, sobre o qual está disposto um revestimento de emissão (3), sendo que o trabalho de emissão fotoelétrica do material do revestimento de emissão (3) é menor que aquele do material de suporte (1) ou menor que 5.6^ *10^ -19^ Joule/elétron. O revestimento de emissão (3) pode conter, em particular, ítrio. O eletrodo, de preferência, possui a forma de um corpo oco e pode estar embutido em um corpo de vidro (8).
