本實驗室研究以自蔓延高溫燃燒合成法製備氮化鋁已有相當長的時間。此方法之可行性與鋁粉形態有密切相關，先前實驗室所用之鋁粉主要為片狀鋁粉，經過實驗室過去多年開發後，目前已可以使用片狀鋁粉進行燃燒合成並且能穩定生產產物量級至少5 kg級且轉化率達99.9%的氮化鋁。然而，由於此種鋁粉價格較高，不利於工業化生產，為使開發出來的氮化鋁合成技術能夠應用於工業化生產，必須使用低價位鋁粉開發氮化鋁合成技術，以達到降低成本之目的。緣此，本論文研究係以開發低成本鋁粉燃燒合成氮化鋁為目標。吾人選用低價位球形鋁粉進行燃燒合成製程開發，且參考過先前學長們的實驗結果，探討先前本實驗量產開發所遭遇的問題並提出解決方案而能達到6 kg級量產開發。在使用球形鋁粉合成氮化鋁之實驗中發現，要能進行燃燒合成反應，不僅引燃能量必須提升且需穩定供應熱源，另一關鍵的問題是鋁粉本身的堆積密度。基於此，本論文研究使用兩種鋁粉相混以有效地改善球形鋁粉本身高堆積密度的特性，本論文研究因而解決了球形鋁粉本身難以引燃且反應容易中斷的問題，並提升產物量級至6 kg級，產物之整體轉化率為99.08%，產率為99.17%。在本論文研究中，吾人也另外找尋了一種價格低廉且較低堆積密度的球形鋁粉，並進行量產製程開發，已可穩定將產物量級提升至6 kg級，且藉由改變壓力、加入添加劑等方法，提高量產級產物之轉化率，在8 atm下6 kg級產物整體轉化率99.29%，產率為99.01%。

In our laboratory, we have studied the preparation of aluminum nitride by self-propagating high-temperature combustion synthesis for a long time. The feasibility of this method is closely related to the shape of the aluminum powder. The aluminum powder used in the past was mainly flake aluminum powder. After few years of development in the laboratory, the flake aluminum powder can now be used for SHS combustion synthesis and stably produce aluminum nitride with a product level of at least 5 kg and a product conversion rate of 99.9%. However, due to the high price of such aluminum powder, it is not advantageous for industrial production. In order to make the aluminum nitride synthesized by combustion be used to industrial production, it is necessary to use low-priced aluminum powder to develop aluminum nitride synthesis technology to reduce costs. For this reason, the research of this thesis aims to develop for using low-cost aluminum powder to synthesized aluminum nitride. We use low-cost spherical aluminum powder for combustion synthesis process development, and refer to the experimental results of seniors, and discuss the problems in the previous mass production development, and propose solution, then we can achieve 6kg mass production development. In the experiment of using spherical aluminum powder to synthesize aluminum nitride, it was found that the combustion synthesis reaction is able to carry out, not only the ignition energy must be increased and the heat source must be stably supplied but the key is the bulk density of the aluminum powder itself. Based on this conclusion, the research uses two types of aluminum powder to mix together, then can effectively decrease the high bulk density of the spherical aluminum powder itself. This method solves the problem that I have mentioned above and also improves the product level of 6 kg, and the overall conversion rate of the product is 99.08%, and the yield rate is 99.17%. In this study, I also searched for a low-cost and low bulk density spherical aluminum powder, and developed the mass production process, which can stably achieve the product level of 6kg. Changing the pressure, adding additives and other methods in the combustion synthesis process can improve the conversion rate of mass-produced products. The overall conversion rate of 6 kg-level products at 8 atm is 99.29%, and the yield of the product is 99.01%.
