The results indicate that arc melting is a good method to produce nb - si system intermetallics due to its simpler technics , lower cost and compact products . however , powder metallurgy is found to be not suitable to produce the nb - si system intermetallics due to its coarse and loose products resulting from the poor molding property of nb and si mixed powders . optical floating zone technology , which is used to fabricate nb - si intermetallic composites for the first time , is also found to be a good way to produce nb - si system intermetallics because of its compact products and good property despite of its relatively high cost 結果表明，電弧熔煉方法制備得到的nb - si系金屬間化合物比較致密，且制備工藝簡單，經濟實用，是一種合適的nb - si系金屬間化合物制備方法；由于nb 、 si元素粉末的成型性很差，用粉末冶金方法(熱壓燒結和冷等靜壓)制備的nb - si系金屬間化合物表面粗糙、致密度低，且成本較高，不宜用于制備nb - si系金屬間化合物；首次用光學懸浮單晶生長技術制備的nb - si系金屬間化合物復合材料致密度很高，盡管成本稍高，但由于性能最佳，也是一種合適的nb - si系金屬間化合物制備方法。
