A Mo&#x2014;Cu composite powder is provided which is comprised of individual finite particles each having a copper phase and a molybdenum phase wherein the molybdenum phase substantially encapsulates the copper phase. The composite powder may be consolidated by conventional P/M techniques and sintered without copper bleedout according to the method described herein to produce Mo&#x2014;Cu pseudoalloy articles having very good shape retention, a high sintered density, and a fine microstructure.

A Y.sub.3 Al.sub.5 O.sub.12 :Tb and method for producing the phosphor are disclosed. The method invloves forming a uniform mixture of source materials for Y.sub.3 Al.sub.5 O.sub.12 :Tb phosphor and barium fluoride with the barium fluoride being present in the mixture at a level of from about 0.254 to about 7.61 weight percent, and firing the mixture at an elevated temperature to react the source material to form the phosphor. The phosphor has an improved brightness of at least about 75% over a phosphor of the same type produced without the barium fluorides.
