Obtenção e caracterização de fosfatos de cálcio pelo método sol-gel.

Abstract

With advancing technology, there is currently an increase in life expectancy due to increased quality of life . This fact has brought other challenges among which the human aging -related diseases such as osteoporosis . This degenerative disease causes a decrease in bone density and therefore greater exposure to fractures . To answer this demand tissue engineering seeks to develop methodologies for the regeneration of bone, making the use of devices that use calcium phosphates, such as hydroxyapatite , Tricalcium Phosphate , Phosphate tetracalcium , which will be obtained in this work with different sintering temperatures , which will be studied and analyzed the possible use of calcium phosphate for bone regeneration. Thus , it is considered pertinent to study synthetic routes for the production of these raw materials . The present work is to study one of these routes , the sol-gel method is one of these methods to establish the optimum conditions for producing calcium phosphates for medical applications .
