Abstract

One vacuum seal system for Field Emission Devices (FED) involves the use of vitreous lead solder glass (frit). Failure analysis of a frit seal problem showed that the decreased seal strength was due to a poor frit bond to the cathode. This prompted an investigation into finding an interim material that would assist in that bond yet would not in itself degrade the vacuum seal integrity. The material used was potassium silicate.
