摘要： A method of microwave synthesis of phosphors includes a microwave furnace having a microwave chamber; providing starting material in the microwave chamber; and subjecting the starting material to microwaves, whereby the starting material is synthesized into phosphors. An insulation package for use in microwave synthesis is disclosed that includes an insulator having an opening therein, wherein the opening is substantially symmetrically disposed in relation to a central axis of the insulator, and wherein the opening is adapted to receive starting material. A susceptor configuration may be positioned within the cavity, wherein the insulator, the cavity, and the susceptor configuration are substantially symmetrically disposed in relation to an axis of rotation of the insulation package. A microwave furnace for continuous microwave synthesis of phosphors is also disclosed.

摘要： A low expansion ceramic composition is represented by the formula Ca.sub.0.5 Ti.sub.2 P.sub.3 O.sub.12 in which up to 100 percent of the Ca is replaced by one or more of the other alkaline earth metals and alkali metals, the alkali metals being selected from the group consisting of Na, Li, K and combinations thereof and substituted in the ratio of two units of alkali metal for each unit of Ca replaced. Up to 100 percent of the Ti is replaced by one or more members selected from the group consisting of Zr, Sn, Nb, Ta and Cr. For each unit of Cr replacement an approximately equal unit of alkali metal is added. For each unit of Nb and/or Ta replacement an approximately equal unit of Na and/or K replaces a unit of Ca. Up to 100 percent of the P may be replaced by Si and/or S. The total of the amounts of Ca, other alkaline earth metals, Li, K, Ti, Sn, Nb, Ta and Cr is greater then zero. Preferably up to 100 percent of the Ca is replaced by Na, and up to 100 percent of the Ti is replaced by Zr or NaCr. The ceramic composition is especially suitable for optically reflecting films.
