一、前言由于钽具有良好的电器特性,近年来钽电容器的生产发展很快。例如:美国和日本所生产的金属钽有50%以上是用于制造电容器。钽电容器的电极引线由钽丝制作,称为引线钽丝。钽电容器具有高度的可靠性,其单位体积电容值比其他型号的电容值高5倍,钽制电容器的体积小,重量轻而容量大,因而广泛地用于导弹、卫星、飞机和宇宙航行上。目前我国生产耐高压的引线钽丝已取得了很大成绩,但在表面光洁以及脆性方面尚不能 I. Preface As tantalum has good electrical properties, the production of tantalum capacitors has developed rapidly in recent years. For example, more than 50% of tantalum metal produced in the United States and Japan is used to make capacitors. Tantalum capacitor electrode lead made of tantalum wire, known as the lead tantalum wire. Tantalum capacitors are highly reliable with 5 times higher capacitance per unit volume than other models. Tantalum capacitors are small, lightweight, and large-capacity, making them widely used in missiles, satellites, airplanes and space launches . At present, China’s production of high voltage lead tantalum wire has made great achievements, but in terms of smooth surface and brittleness can not yet
