Hi The Russians developed the material back in the late 60's. They were trying to sell it in the US by the mid 70's through Raychem. They had limited success peddling it. The gotcha was the fabrication accuracy. I don't know the name / location of the Russian institute that did the actual fabrication.
They have continued to develop OCXO's based on the stuff at least into the late 90's. Some of those parts are pretty high performance units. You might find some data on the Morion web site. I suspect there is a reasonable body of papers on it all in Russian. They did a *lot* of research and development on the material and the OCXO's.
