(I) 複数の粒子を気密封止可能なバッグに詰め込む工程、
(II) バッグ内部から気体を排出する工程、
(III) バッグを気密封止する工程、及び
(IV) バッグを、少なくとも1000mの深さを有する水柱内に、水柱の表面下少なくとも1000mの圧縮場所まで降ろす工程、
を含み、
上記工程により、等圧圧縮生地体が形成される、
方法に向けられる。
(V) 工程(IV)において得られた生地体を、緻密セラミック体を得るため、望ましくは標準大気圧の下で、1000℃より高い温度で焼結する工程、
を含む。
(IV.1) 気密封止されたバッグをケージ内に入れる工程、及び
(IV.2) ケージを水柱表面から圧縮場所まで降ろす工程、
を含む。
(IV-A) 工程(IV)後にバッグを水柱表面の上まで引き上げる工程、
を含む。
P=ρ・g・h
にしたがって計算できることが知られている。ここで、ρは水柱の密度であり、gは重力加速度であり、hは水柱の高さである。したがって、海が圧縮場所において深くなるほど生地体にかかる圧力は高くなる。生地体にかかる圧力が高くなるほど生地体は強く圧縮され、粒子充填密度が高くなる。極めて緻密な焼結セラミック体を作製するためには、圧力場所が海水面下少なくとも8000mであることが望ましく、いくつかの実施形態では少なくとも9000m、いくつかの実施形態では少なくとも10000mである。海水面下10000mにおいて、圧力は約16kpsi(1.1×108Pa)である。
