摘要
Biocomposite materials with a gradient pore structure based on a silicate feldspar matrix and hydroxyapatite are analyzed. Porosity and pore size intervals are determined with respect to implants used in neurosurgery, taking into account differences in the process of osteogenesis occurring on different surfaces. In contrast to osteoconductive calcium-phosphate biocomposites with a uniform pore structure, a gradient pore structure provides for a multiple increase in strength of materials.
