本論文乃探討如何將鈣硼矽玻璃粉末在水溶液中有效的分散。首先針對實驗中所使用的鈣硼矽玻璃粉末之基本性質作深入地了解。發現此玻璃粉體在水溶液中之表面電位大致上為負值，因此我們在選用分散劑時，則以帶有正電的聚乙烯胺(PEI)作為使用之首選。
進一步我們利用本質黏度及小角度x光散射法測量PEI在不同pHeq值之水溶液中的旋轉半徑，發現其大小會隨溶液pHeq值的減小而增大。然而量測PEI在粉體表面之吸附量後由公式推得之PEI旋轉半徑，則與前述結果有所出入。經分析後發現，由於在酸性溶液中，粉體會有大量的Ca2+、B3+離子溶出，造成PEI有團聚結構，而使此時PEI的吸附量異常變大。
而就CBSG漿料流變行為，則由粉體溶解及PEI的帶電情形作匹配，可在漿料之pHeq= 7.8 - 10.6的區間中，得到使漿料穩定所需之PEI添加量的穩定分佈圖。然改變漿料固含量亦會影響穩定分佈圖之分佈。由結果發現，PEI與CBSG漿料系統之最大穩定固含量約為45vol%。
