Abstract
The present embodiments disclosed herein are related to methods of preparing a macroporous ceramic body. According to some embodiments, a first mixture of ceramic-forming components is combined with a polymer network structure to form a second intermediate mixture comprising a polymer network. The polymer network is then removed in the drying and/or sintering step leaving an interconnected open pore network within the ceramic body. In some embodiments, the macroporous ceramic body comprises a three-dimensional, porous network comprising pores of about 3 mm to 11 mm.
Claims14
A method of preparing a macroporous ceramic body having a three-dimensional porous network, comprising the steps of:
- combining a first mixture comprising ceramic-forming components with a three-dimensional polymer network structure to form a second intermediate mixture comprising a polymer network, wherein the three-dimensional polymer network comprises a polymer bead and wherein the polymer bead has a coating of polyurethane;
- and
- drying and sintering the second intermediate mixture to prepare the macroporous ceramic body, wherein the three-dimensional polymer network comprises interconnected, three-dimensional figures.
