粒度準備
英文
size preparation-
For adapting to the need of industrialization and improving the properties of materials, the method of mechanical activation has introduced on the basis of traditional calcinations at high temperature. the stardard spinel limn204 is prepared by the mechanical activation - high temperature solid synthesis method. the thermodynamic property, the physical - chemistry performance and the producing techniques of. battery have been studied by means of thermogravimetry ( tg ), differential scanning calorimetry ( dsc ), x - ray diffraction ( xrd ), scanning electric microscopy ( sem ) as well as various electrochemical analysis methods. studies show that synthesis temperature, calcinations time, recipe of raw materials, heat treatment and particle size of products are main factors affecting the performances of limn204 cathode materials. with the increment of synthesis temperature and time, the structure and crystal of products are getting to perfect
隨著合成溫度和時間的增加，產物的結構和晶型越趨于完善，但在1100得到的產物有燒結和晶粒增大的現象，恆溫時間超過24h后對材料的性能影響不是很大； li mn比在0 . 95 1 . 05 2的條件下都可得到標準的尖晶石limn _ 2o _ 4 ，尤其當li mn比為1 . 05 2時，所合成的材料具有較好的電化學性能；通過兩段合成法制備的產物性能要比一段合成法法制備的產物性能好，而兩段間隔合成法比兩段連續合成法處理的材料性能更佳；顆粒的粒度隨著球磨時間的延長而減小，比表面昆明理工大學碩士學位論文摘要卻增大，粒度小且分佈范圍窄的材料有利於鏗離子的擴散。Standard practice for preparation of airborne particulate lead samples collected during abatement and construction activities for subsequent analysis by atomic spectrometry
