Cengiz M. etal, "Sublimation growth and characterization of bulk aluminum nitride single crystals", Journal of Crystal Growth 179, 1997,p.363-370 Glen A. Slack, "Growth of Single Crystals", Mat. Res. Soc. Symp. Proc. Vol.512, 1998, p.35-40
実施例1として、開口部形成部を含め、全体を窒化チタンで形成した単結晶の原料が収容される容器を作製した。具体的には、粒度分布が0.5〜2μmの窒化チタン粉末を金型成形法により、20MPaの圧力で成形した。成形体を窒素ガス中でホットプレス法により、1800℃で焼成した。得られた焼結体に研削加工を施し、容器を得た。
