Keeping the temperature at 200 ? for 48h, that the ratio of sulfur and tin was 1 : 4 could obtain the sns2 nanobelts, and that the ratio was 1 : 10 could obtain the sheet - like sns crystals. moreover, using the ratio of 1 : 4 at 160c for 24h could obtain the leaf - like sns2 nanostructures. star - shaped and rod - like pbs nanostructures were also synthesized by thioglycolic acid assisted hydrothermal process
當反應溫度200和反應時間48小時保持不變時，錫硫摩爾比為1 ： 4可以得到sns _ 2納米帶；錫硫摩爾比為1 ： 10則為sns薄片狀結構；而摩爾比低於1 ： 4時，產物中還有sno _ 2顆粒存在。Dispersivity and stability of antimony doped tin oxide nanoparticles in ethylene glycol solutions
銻摻雜納米二氧化錫顆粒在乙二醇中的分散穩定性( 3 ) the most principal factors that influence the supersonic atomization process include the flow ratio of the gas - liquid metal ( gmr ) value, the flow of atomizing of gas and the range of the inverse vortex taper. the more of the value of three factors, the more advantage they are for the atomization and the more fine the powders are. ( 4 ) the produced powders are the best in efficient atomization efficiency, particle diameter, particle shape and dispersion when the solder alloy is zhl63a, atomizing medium is n2, the protrusion h = 6. 0mm, atomizing gas pressure p = 100mpa, over - heat temperature t = 167 ( t = 350 )
研究結果表明： （ 1 ）超音速霧化器的氣體流場在導液管下端形成一個倒渦流錐，在二維空間上呈軸對稱的雙峰分佈，負壓形成於這個倒渦流錐內； （ 2 ）修正後的霧化氣體速度公式可以滿足超音速霧化的要求； （ 3 ）影響超音速霧化工藝最根本的因素有氣液質量流率比（ gmr ）的大小、霧化氣體流量和倒渦流錐范圍，三個因素的值越大，對形成細粉越有利； （ 4 ）在焊錫合金為zhl63a ，霧化介質微n _ 2 ，導液管突出高度取h = 6 . 0mm ，霧化氣體壓力取p = 1 . 0mpa ，合金過熱度取t = 167 （ t = 350 ）時，所制得的粉末在有效霧化率、顆粒球形度、粒度及其離散度三個方面綜合性能最好。With the contrast of same product of abroad, it is very small to possess the particle diametre, the good characteristic of scattered nature
