The basic methods of manufacturing porous glass and glass-ceramic materials were examined and analyzed on the example of bioactive materials for bone endoprosthesis. The possibility of using sol-gel technology for forming porous structures with the 3D model developed was demonstrated.Inorganic porous materials such as foam concrete, foam glass, and claydite are widely used for fabricating load-bearing structures, heat and sound insulating panels, and heatsaving elements due to the macroporous structure with pores larger than 1 mm. Ceramic materials that have high resistance to different aggressive media and a microporous structure, with a pore size range from several micrometers to 1 mm, are frequently used for filtering and catalytic systems. The pore sizes in polymeric, ceramic, and glass molecular sieves, membranes, and filters for separation of biological systems are comparable to the size of cells and proteins. Macro-and microporous materials are obtained with the well-known and well developed methods of sintering, foaming, or duplication, while nanoporous materials usually require development of new, original manufacturing methods [1].The new approaches to fabricating materials with a defined pore structure and porosity type can be traced on the example of bioactive materials for bone endoprosthesis based on calcium phosphates and silicate and phosphate glasses. The analysis and generalization of world advances in creating and using new medical implant materials indicates their broad possibilities and prospects for development. According to the estimations of experts, more than 600,000 bone operations are performed in the world: up to 300,000 in the US and more than 100,000 in Russia. The overall market for biomaterials in the leading countries of the world is estimated as follows (2003 data): USA -$1.16 billion; Japan -$430 million; Europe -$230 million. The predicted increase in this sector is a minimum of 20% a year.The last generation of biomaterials for bone endoprosthesis -the "truly intellectual" generation [2] -is manufactured by growing living cells of a certain type on a biomaterial substrate and then introducing them in the body as a unified cell-biomaterial structure. The role of the support is played by bioactive ceramic, glass, glass-ceramic, or composite materials whose structure is formed so that the cells required for formation of some type of tissue can penetrate, be attached, and grow in contact with the tissues in the living medium. The structure of the biomaterial means the level and character of the porosity and the pore shape and size. Penetration of bone cells in the support is only possible when the pores are a minimum of 150 mm in size, and the pores must be open and approximately 500 mm in diameter for formation of a vascular system that will maintain the vital activity of these cells in the implant.The currently most common methods of fabricating glass, glass-ceramic, and composite porous materials are shown in Fig. 1. The methods traditional in glass technology (etching of the s...
