Preparation of the BaO-B₂O₃ Matrix Low-Temperature Sintering Ceramics via an Aqueous Suspension Route

Abstract:

Due to the low-meting characteristics of the BaO-B₂O₃ binary composition, the dense ceramics with peculiar properties, so called low-temperature sintering ceramics, were prepared by the introduction of other oxides, e.g., SiO₂, Al₂O₃, ZnO, CaO to the BaO-B₂O₃ binary compositions at a sintering below 1000°C. The low-temperature preparation of the ceramics are achieved by milling the aqueous suspension mixtures of Ba (OH)₂·8H₂O, H₃BO₃ ,H₂SiO₃, Al (OH)₃, ZnO. By the aqueous suspension process, some compounds with a low-melting point such as hydrated barium borate, and the precursor compounds of the functional mineral phases, e.g., BaSiO₃, ZnSiO₃, BaAl₂Si₂O₈, etc. can be formed easily from a suspension solution, which consequently supply more possibilities to fabricate the low-temperature sintering ceramics with peculiar physical properties.
