Estudio del proceso de sinterización de zeolitas ZSM-5 con otros compuestos biocerámicos. Conformación a través del proceso de freeze casting para piezas para regeneración de tejidos óseos

Zeolites are aluminosilicates widely known at a scientific and industrial level because of the great specific surface area they present. Thus, zeolites can be used to storage inside of them different compounds. In this way, zeolites could be a sustained deliver biomaterial of drugs or other molecules that could promote the tissue regeneration as, for example, bone tissue. Although, as any other ceramic compound, zeolites need to be sintered to be conformed as a solid material. This thermal process provokes changes in their inner structure and also modifies their specific surface area. In order to be able to conform this material as a solid sample and, at the same time, keep its high values of specific surface area, this study proposes to mix zeolites with other bioceramic compounds that also present bone tissue regeneration properties as bioactive glass 1393 (BG 1393) and biphasic calcium phosphates, formed by 60% of hydroxyapatite and 40% of beta tricalcium phosphate (60%/40% HA/β-TCP).
