  • Bio-material and method of preparation thereof
    Patent number: 8052787
    Abstract: A porous bio-material and a method of preparation thereof. The method includes the following steps. First, a body is formed by mixing a bio-ceramic powder, a water-absorbing natural organic material and a liquid. The water-absorbing natural organic material is selected from the group consisting of carrageenan and agar. Then, the body is partially dried to form a machinable porous bio-material. The sizes of pores and porosity can be tailored by controlling the extent of drying so that the porous bio-material with acceptable strength can be obtained.

    Publication number: 20090088311
    Abstract: A porous bio-material and a method of preparation thereof. The method includes the following steps. First, a body is formed by mixing a bio-ceramic powder, a highly water-absorbing natural organic material and a liquid. Then, the body is partially dried to form a machinable porous bio-material. The sizes of pores and porosity can be tailored by controlling the extent of drying so that the porous bio-material with acceptable strength can be obtained.
