Процеси змочування перовськітової BaTiO3-кераміки металічними розплавами
The complex research of the contact interaction and wetting of BaTiO3 - perovskite ceramics by metal melts is carried out. Two states of barium titanate were studied: 1. semiconducting BaTiO3−x - with oxygen defect. The experiments in vacuum for 13 pure metals and for Ti-containing alloys Cu−Sn−Ti,...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The complex research of the contact interaction and wetting of BaTiO3 - perovskite ceramics by metal melts is carried out. Two states of barium titanate were studied: 1. semiconducting BaTiO3−x - with oxygen defect. The experiments in vacuum for 13 pure metals and for Ti-containing alloys Cu−Sn−Ti, Cu−Ga−Ti and Ag−Cu−Ti are executed. The majority of metals do not wet barium titanate. The addition of Ti sharply increases capillary properties and adhesion; 2. ferroelectric stoichiometric BaTiO3. The studies of alloys Ag−Cu−O in air are carried out. Oxygen dissolved in alloy Ag−Cu works as a strong adhesive element. Compositions of capillary active alloys and modes of brazing and metallization of barium titanate with high strength of a contact are recommended. |
