摘要

A method of joining ferroelectric, optical and other non-metallic materials, such as lithium niobate, quartz, TlBr-TlI, glass, etc., at room temperaure under a pressure of 0.1/0.5 MPa is described. The surfaces to be joined are prepared to optical flatness, and indium or lead coatings as bonding agents are used. To obtain clean surface,s procedures of the coating deposition and sample joining are performed in situ in a vacuum of 10~-4 Pa. The strength of the obtained joints is about 20MPa for indium coatings and about 30MPa for lead coatings. It is supposed that attractive surface forces play a decisive role in the contact formation and bonding of the wafers. The method has been applied for joining of LiNbO_3/TlBr-TlI, quartz/quartz and other materials to make acoustooptical and electroacoustic devices.
