基於本研究室先前在製程方面之研究結論，合金粉末經過熱處理對於汞齊合金性質之提升有很大的幫助，故本實驗自行配料，由美國HJE公司協助以不同噴塗變數製成不含鈀單成分汞齊合金粉末AT1、AT2、AT3與含鈀單成分汞齊合金粉末ATP1、ATP2、ATP3，經過熱處理後探討不同噴塗變數對含鈀與不含鈀汞齊合金之影響與差異，並由不同噴塗變數中，設計出低汞釋出、操作性優、高機械性質之汞齊合金。
實驗結果發現不同的噴塗變數對於合金粉末之大小、形狀與表面型態有粉大的影響，而合金粉末直接影響汞齊合金之汞齊化反應，故在機械性質方面而言，AT2與ATP2其抗壓強度與徑向拉伸強度上升的趨勢與另外2個變數不同，並發現合金顆粒越小，其反應越完全，對於各分面性值的提升越有幫助。而含鈀汞齊合金方面，ATP1由於γ2相的生成，對其性質之影響甚鉅，而在AT2、AT3中改善其γ2相的產生，故在性質上有很大的改善。

Base the research about process parameter before ,we could find many records about heat treatment ,there are great help to the improvement of the properties , in this study , HJE Company in U.S.A , helped to made the amalgam that without Pd (AT1、AT2、AT3)and with Pd (ATP1、ATP2、ATP3) by different process parameter .After heat treatment to find the differences and effects between three kinds of process parameter in amalgam without Pd and that with Pd ，in different process parameter to design the amalgam with low mercury release、good operating 、high mechanical .
Experimental result finds the process parameter has significant different in powder size、shape and surface form , and the powder effects the amalgamation in amalgam directly . In mechanical propriety , AT2 and ATP2 have different way to get strength in compression strength and diametrical tension strength . The smaller practical size the reaction of amalgam are more completed , and useful to the improve of propriety .
For the composition with Pd , the γ2 phase forms in ATP1 , there are large effect in it’s propriety . ATP2 and ATP3 reduce the form ofγ2 phase , properties has large improvement .
