| Outline of Final Research Achievements |
A method to produce glass/glass lap joints with bond interfaces transparent to visible light by anodic bonding with a conductive intermediate layer was developed. Joints of soda-lime glass and several types of optical glasses with transmittance of 70-80% for visible light were achieved by using aluminum or titanium as materials for the intermediate layer, and setting bonding condition and thickness of intermediate layer appropriately. In joints with high transmittance, the conductive intermediate layer was consumed by oxidation, and electric conductivity of the bond interface in such joints became high. In the course of study, appropriate condition for anodic bonding of titanium to various types of glasses and tanning phenomenon of some glasses by applying electric current were found.
