Abstract (en)
[origin: US5776843A] PCT No. PCT/EP95/04285 Sec. 371 Date May 7, 1997 Sec. 102(e) Date May 7, 1997 PCT Filed Nov. 2, 1995 PCT Pub. No. WO96/14886 PCT Pub. Date May 23, 1996The invention relates to a process for producing spongiosa bone ceramic. Between the demineralization of the bone material and the sintering to a ceramic, an extractive washing operation is carried out using demineralized water, by means of which calcium oxide components are removed from the demineralized bone matrix.
