채용미파소해-ICP—AES법측정고기합금중붕원소。통과시험탐토료고기고온합금중기체원소，주량원소여락、오、목등대붕원소분석보선적광보간우정황，채용기체필배법대기체간우진행교정，학정료합괄적분석보선。방법적선성범위위0～8mg／L，검출한위0．0003％。측정결과적상대표준편차위1．88％-6．04％（n=6），회수솔위92．0％～104．2％。
Boron in coblat based superalloy was determined by microwave digestion and ICP - AES. The spectral interference of matrix and coexist elements such as chromium, tungsten, molybdenum were studied. Calibration was made with matrix, and analytical lines were selected. The linear range of the method were 0 - 8 mg/L, and the detection limit was 0.0003%. The relative standard deviations of determination results were 1.88% -6.04% （n = 6） and the recoveries ranged from 92.0% to 104.2%.
