Abstract
A transparent, complex oxide ceramic having the formula: EQU (Sr.sub.1-x Me'.sub.x) (Li.sub.1/4 Me".sub.3/4) O.sub.3 wherein x is 0.01-0.50, Me' is at least one metal selected from the group of Ca, Ba, and Pb, and Me" is Nb and/or Ta. The present ceramics can be used in the fabrication of gas discharge tubes and for infrared-ray tubes as optical devices and as substrates for higher quality electronic parts, and as an insulator for microwave frequency electronic devices.
