Description
0.3−5.0m2/g間の範囲で比表面積を持つ異なる粉末は、引張試験のための試験の製造に用いられている6mm形を持つロッドに400℃での押出成形によって熱間加工された。その結果は、表および図6(a)および図6(b)に示す。これは、微細粒子分布(高表面積)より良好機械的特性を証明する。粉末は、狭いノズルシステムを用いるガス噴霧を通して製造され、かつ空気分粒を通して要求されるPSDに分級される。それから、コンパクトは400℃、R11:1での押出成形によって製造される。高温引張試験は、試験温度で30分の浸漬時間後なされる。
引張試験片は、加工され、かつASTM E 8およびASTM E 21に従って試験される。
