Influences of phase composition on Sr3SiO5:Eu2+ luminous performance王晓春,张希艳,王辰,秦伟达,孙佳逊Engineering Research Center of Optoelectronic Functional Materials of the Ministry of Education,Changchun University of Science and Technology摘 要:α’-Sr2SiO4 :Eu2+ phase always coexists with the Sr3SiO5:Eu2+ phase when it is synthesized by a high-temperature solid-state......
. Key words: nanocrystalline material; zirconia; thermal barrier coating; heat treatment; phase composition 1 Introduction Hundreds of different types of coatings are used to protect a variety.... This is a cubic phase. Composition of the cubic phase is Y0.15Zr0.85O1.93. This result tells us that all monoclinic/tetragonal phases in the nano-powder feedstock have transformed to cubic phase......

forming systems was summarized. The so-called cluster line in a ternary phase diagram refers to a straight composition line linking a specific binary cluster to the third element. The compo- sition ranges of quasicrystals and bulk metallic glasses can be determined by the direct use of cluster lines, where two cluster lines intersect at the optimum phase forming composition. Furthermore......
