Abstract
Inventia se refera la o sticla electrodica pentru electrod de pH din sticla, cu eroare alcalina si acida minima, a carui membrana este confectionata din aceasta sticla. Se stabiliste o compozitie avantajoasa de sticla electrodica bazata pe sistemul oxidic SiO2-TiO2-Li2O-BaO-La2O3-CeO2, cu proprietati îmbunatatite de prelucrare. Sticla poseda, totodata, o înaltî stabilitate chimica si o buna compatibilitate cu sticla de plumb, datorita coeficientilor de dilatare termica suficient de apropiati ai celor doua sticle. Electrozii de pH realizati ca membrana din aceasta sticla sunt, practic, lipsiti de eroare alcalina la pH = 13 si, respectiv, de eroare acida la pH = 0. Exista posibilitati de aplicare, atît în ceea ce priveste obtinerea sticlei electrodice de pH cu membrana din aceasta sticla.
