AMTとAPTはどちらもタングステン酸アンモニウム化合物ですが、用途には明確な違いがあります：
触媒分野：AMTは高い溶解性により溶液含浸プロセスに適しており、APTは焼成法によるタングステン系触媒の製造に多く使用されます。
• タングステン化合物：AMTはWO₃や微細タングステン粉末の製造において効率的ですが、APTは粗タングステン粉末やタングステン合金の生産で主に使用されます。
• 特殊用途：AMTは電気化学や難燃用途で優れており、APTはこれらの分野での使用が少ないです。
例えば、高純度WO₃を必要とする電子工場では、プロセスが簡単なAMTを選択しますが、タングステンロッドを製造する冶金工場では、大規模な固体還元に適したAPTを優先します。
