Abstract
【解決手段】d50が0.9〜1.5μm、d75/d25が3〜8であり、エタノール吸液量が粉末5g当たり2.0〜2.3mlである窒化珪素粉末。ここで、d50とはレーザー回折散乱法で測定された粒度分布における累積50体積%径、d75とは累積75体積%径、d25とは累積25体積%径のことである。また、本発明の窒化珪素粉末の焼結体からなる窒化珪素焼結体。さらに、本発明の窒化珪素焼結体で構成された非鉄金属の溶湯用部材。
【選択図】なし
Description
金属珪素粉末の直接窒化法(例えば特開平2−44017号公報の実施例1参照)にてα率90%以上の窒化珪素インゴットを製造した後、それをジョークラッシャーにて粗砕、更にチューブミルと振動ミルで中砕・微粉砕した後、気流式分級機で分級し、表1に示される窒化珪素粉末を製造した。窒化珪素粉末の粒度調整は、振動ミルのフィード量、分級機の一次エアー量と二次エアー量の制御によって行った。得られた窒化珪素粉末につき、上記方法に従い、d50、d75/d25及びエタノール吸液量を測定した。また、窒化珪素粉末の充填性として、窒化珪素粉末を金型プレス成形後98MPaの圧力でCIP成形し、アルキメデス法によりCIP成形体の相対密度を測定した。それらの結果を表1に示す。
