進出口鎢酸鈉中鎢酸鈉含量的測定In 1958, ganzhou concentration plant was established and started its production. after 1963, tungstic acid, apt, w powder, wc powder and cemented carbide could be produced too
1958年，贛州精選廠建成投產。 1963年以後，進一步發展到生產鎢酸、鎢酸鈉、仲鎢酸銨、鎢粉、碳化鎢粉、硬質合金等。It is well known that wo3 is a conductance - type semiconductor gas sensing material, but the research on fish freshness detector with wo3 - based gas sensor to trimethylamine is still at a beginning stage. in this project, the wo3 - based gas sensors to trimethylamine are made, and their gas sensing performance are researched, especially at low temperature, the results are as follows : 1. the nano - sized wo3 powder is prepared by sol - gel method of sodium tungstate and hydrochloric acid, and its microstructure is analyzed by using xrd, sem and tem, for material ’ s microstructure is closely related to gas sensing performance
本課題制備了wo3材料，並以它為基材，製作了三甲胺氣敏傳感器，研究了其對三甲胺的氣敏性能，尤其是低工作溫度下的氣敏性能，得到結果如下: 1 、本課題以鎢酸鈉和濃鹽酸為反應物，用溶膠凝膠法制備了納米wo3材料，並採用x射線衍射分析儀（ xrd ） ，掃描電鏡（ sem ） ，透射電鏡（ tem ）對該材料進行結構分析和形貌觀察，研究發現材料的微觀結構與氣敏性能緊密相關。The relation of absorption of nano - metal sols and the addition of dispersants, as well as the rule of absorption of nano - metal sol added by dispersants concomitant to placing time were systematically investigated by means of uv - vis. the results show that, the suitable dispersant to nano - iron / ethanol sol is 0. 035 % polyoxyethylene ( 10 ) lauryl ether ( op - 10 ), but in the case of nano - tungsten / ethanol sol, 0. 13 % neotelex maybe is of more benefit to its disperse stability. the observation of tem shows the best evidences
Uv - vis法理論分析結果表明，對于納米鐵溶膠，添加0 . 035的非離子型表面活性劑十二烷醇聚氧乙烯醚可以達到良好的分散穩定性；而對于納米鎢溶膠，最理想的分散劑則是0 . 13的陰離子表面活性劑十二烷基苯磺酸鈉，電鏡觀察結果完全證實了該推論，顯示5天後的納米金屬溶膠仍然保持良好的分散狀況。Methods for chemical analysis of ferrotungsten - the sodium periodate photometric method for the determination of manganese content
鎢鐵化學分析方法高碘酸鈉光度法測定錳量Methods for chemical analysis of tungsten concentrates - the hydrochloric acid - sodium chloride supporting electrolyte polarographic method for the determination of lead content
