Abstract: Electro-static dissipative or ESD materials must possess sufficient conductivity to allow for the dissipation of static charges while maintaining enough insulating characteristics to prevent shorts. Described here in are ceramic ESD materials comprised of stabilized zirconia and lanthanum chromate.
Abstract: The present invention is directed towards a lightweight, sealant-free, thin glass envelope having a front surface and back surface laminated and integrated together, i e. specifically, a unitary envelope body having at least one discharge or ionizable gas channel. The glass envelope exhibits a weight to area ratio of .ltoreq.1.0 g/cm.sup.2. Lightweight, internally channeled light-emitting devices can be formed from these thin glass envelopes by etching electrodes to the envelope, at opposite ends of, and in communication with, the gas channel which contains a discharge or ionizable gas.
