pyrochlore 中文意思是什麼
pyrochlore
解釋
黃綠石-
Under no excess pbo flux environment, the perovskite phase of pmnt single crystals were more stable than that of pznt, but it was found to be the decomposition of perovskite crystals into pyrochlore crystals at 1250. the pure perovskite pznt crystals prepared by the pbo flux method were thermodynamically metastable
在無pbo條件下pmnt晶體較pznt晶體穩定，但在1250附近的高溫下會發生向焦綠石相的分解反應； pznt單晶體是亞穩定的，在高溫時亦分解生成焦綠石相和pbo 。 -
Study on pyrochlore in synthesis process of lead - based relaxor ferroelectrics

The influence of pellet technique and microwave method on the emerge of the intermediate pyrochlore phase was studied
通過壓片煅燒和微波合成等工藝考查了壓片及快速升溫對焦綠石相的生成的影響。 -
The optimum mole ratio of flux to composition was found to be 6 : 4, which can restrain the formation of pyrochlore phase. it was revealed that b2o3 additive played an important role in increasing the size of single crystals. 4
助熔劑和組分間的摩爾配比以6 ： 4為佳，能夠抑制焦綠石相的產生；此外，添加少量的b _ 2o _ 3作助熔劑有利於晶體的長大。 -
The precursor method could solve the problem that the appearance of pyrochlore phase during the synthesis procedure by avoiding the direct reaction between pbo and nb _ ( 2 ) o _ ( 5 ). furthermore it also could decrease calcination temperature and pbo volatility

It seems that a pseudo cubic phase was formed. the pyrochlore phase is effectively restrained in pt / tb powders. fluorescent properties of pt / tb sol and powders were investigated
Tb離子特徵熒光僅出現在pt / tb的溶膠狀態體系，在粉末狀態下tb離子的特徵熒光顯著減弱。 -
As - grown pmnt single crystal were pure perovskite structure and regular pseudo - cubic while pznt showed an arrow - head shape with the formation of pyrochlore phases. 3. processing conditions were optimized in order to increase the size and yield of perovskite crystals by a high temperature flux solution method
制備pmnt單晶時均生成純立方鈣鈦礦相結構，無焦綠石相產生，晶體幾何外形多為規則的立方結構；制備的pznt單晶材料形狀不規則，呈箭頭狀，且伴隨有焦綠石相生成，因此純相的pznt單晶材料較pmnt晶體更難合成。
