Abstract

um eletrodo de referência que é estável em uma ampla faixa de temperaturas, pressões e condições químicas é fornecido. o eletrodo de referência em questão de acordo com a presente invenção compreende um invólucro tubular composto de quartzo tendo uma extremidade distal fechada e uma extremidade proximal aberta. uma haste de cerâmica isolante é aparentemente conectada à abertura na extremidade distal fechada do invólucro para formar microfissuras entre a haste de cerâmica e o invólucro de quartzo (chamado de junção fissurada, cj). a cj gera um caminho muito tortuoso para a condução iônica de dentro do eletrodo de referência (re) para um eletrodo de trabalho (we). dentro do invólucro tubular há um eletrodo (por exemplo, um fio de prata) disposto em um eletrólito que compreende uma mistura de sais de metal alcalino (por exemplo, agcl e kcl), estendendo-se do eletrólito para cima através de um meio de vedação na extremidade proximal do invólucro de quartzo.
