POROUS SUPPORT OF CALCIUM PHOSPHATE CEMENTITIOUS MATERIAL AND ITS USE IN FLUIDIC INSTRUMENTS

摘要

The present invention discloses a porous frit obtainable by a process comprising the following steps: a) preparation of a powder based on calcium phosphates; b) preparation of a cement paste by mixing said powder with a liquid phase; c)pouring said cement paste in a suitable mould; d) compression; e) drying; f) hardening; g) optional extraction from the mould. The frit is used in separation devices, in particular filtration or fluidic devices, also miniaturized.
