Abstract: A liquid junction electrode 10 formed from a silicon body 14 and having a glass membrane 22 attached thereto. A reference electrode is constructed by forming the glass membrane 22 from porous glass having a preferable pore size in the range of 40 angstroms to 75 angstroms. The porous glass membrane 22 has a coating 24 of glass containing mobile ions that is electrostatically bonded to the silicon body 14. Alternatively, a glass plug 92 is formed from a paste of ground glass and organic binder that is heated to cause formation of pores and bonding of the glass plug 92 to a silicon body 94. An ion-sensitive electrode is constructed by forming the membrane 52 from an ion-sensitive glass or by filling the pores of the porous glass membrane 22 with an ion-sensitive material.
