Influence of Flux on Structure and Luminescence of LaMgB5O10:Ce3+,Mn2+ 常树岚1 (1.Department of Chemistry,Science and Engineering College,Yanbian University,Yanji 133002,China) Abstract:The influences of the flux KCl or KF on the XRD patterns,cell parameters,crystal morphology,and spectral properties of the phosphor 12.8% KCl and 5.3%,10.5% KF are added individually into the phosphor......
; pinning effect 1 Introduction Good strength-to-mass ratio, high thermal conductivity, and good corrosion resistance have made aluminum alloys very popular as structural materials. However..., grain size of SZ with SiC particles is decreased to 3 μm. The pinning effect of SiC particles during grain growth impedes the migration of grain boundaries. Decreasing the particle size intensifies......
