21. A solid solution series exists with the high cobalt willyamite. 22. The crystals are a solid solution of 97 % anorthite and 3 % albite. 23. A key need is application of actinide solid solutions in durable crystalline host phases. 24. Heterojunctions of quaternary solid solutions of InGaAsP / InP were investigated under his leadership. 25. Inconel 625 was designed as a solid solution strengthened material with no significant microstructure. 26. Sanidine and high albite constitute a solid solution series with intermediate compositions termed anorthoclase. 27. It forms a solid solution series with scheelite ( calcium tungstate, CaWO 4 ). 28. Superalloys develop high temperature strength through solid solution strengthening. 29. Corkite will also form a solid solution with kintoreite. 30. Lazulite forms one endmember of a solid solution series with the darker iron rich scorzalite.
