超純(chun)金屬(shu)，指的(de)(de)(de)(de)化(hua)學(xue)雜(za)質和物理雜(za)質 (晶體缺陷) 含(han)(han)量(liang)的(de)(de)(de)(de)金屬(shu)。目(mu)前主要以化(hua)學(xue)雜(za)質的(de)(de)(de)(de)含(han)(han)量(liang)為(wei)標準(zhun)，常(chang)以雜(za)質在(zai)金屬(shu)中總含(han)(han) 量(liang)的(de)(de)(de)(de)百萬分之幾表示(shi) 。超純(chun)金屬(shu)是(shi)相對高(gao)純(chun)度的(de)(de)(de)(de)金屬(shu)，一般(ban)指金屬(shu)純(chun)度達(da)到純(chun)度9以上的(de)(de)(de)(de)金屬(shu)，貴金屬(shu)靶材，物理雜(za)質的(de)(de)(de)(de)概念(nian)才是(shi)有意義的(de)(de)(de)(de)。

材(cai)料的(de)純度對其性(xing)能，特別(bie)是(shi)微(wei)電子學、光(guang)電子學性(xing)能影響很大(da)，現(xian)代高(gao)技術產業要(yao)求(qiu)制(zhi)備出(chu)超純金(jin)屬以(yi)利(li)于制(zhi)作(zuo)器件。

濺(jian)(jian)射靶(ba)材(cai)的要求(qiu)(qiu)較傳統材(cai)料(liao)行業高(gao)(gao)，一般要求(qiu)(qiu)如，貴金(jin)(jin)屬(shu)靶(ba)材(cai)多少錢，尺(chi)寸(cun)(cun)、平整度(du)(du)、純(chun)度(du)(du)、各項雜質含(han)(han)量、密(mi)度(du)(du)、N/O/C/S、晶(jing)粒尺(chi)寸(cun)(cun)與缺陷控(kong)制；較高(gao)(gao)要求(qiu)(qiu)或特殊要求(qiu)(qiu)包含(han)(han)：表面(mian)粗糙度(du)(du)、電阻值、晶(jing)粒尺(chi)寸(cun)(cun)均(jun)勻性、成份與組織均(jun)勻性、異物(wu)（氧化物(wu)）含(han)(han)量與尺(chi)寸(cun)(cun)、導磁(ci)率、超(chao)高(gao)(gao)密(mi)度(du)(du)與超(chao)細晶(jing)粒等等。磁(ci)控(kong)濺(jian)(jian)射鍍(du)(du)膜(mo)是一種新型的物(wu)相鍍(du)(du)膜(mo)方式(shi)，就(jiu)是用電子系統把電子發射并聚焦在被(bei)鍍(du)(du)的材(cai)料(liao)上，使其被(bei)濺(jian)(jian)射出(chu)來的原子遵循(xun)動量轉換(huan)原理以較高(gao)(gao)的動能脫離材(cai)料(liao)飛向基片(pian)淀積成膜(mo)。這種被(bei)鍍(du)(du)的材(cai)料(liao)就(jiu)叫濺(jian)(jian)射靶(ba)材(cai)。 濺(jian)(jian)射靶(ba)材(cai)有金(jin)(jin)屬(shu)，合(he)金(jin)(jin)，陶瓷化合(he)物(wu)等。
