RESUMO:

The generation of industrial waste is an obstacle for its management, the ceramic sector stands out as a potential generator. In view of this, the use of this residue is proposed as a source of calcium oxide for the synthesis of Hydroxyapatite (HAp), a bioceramic that requires calcium. Therefore, characterization was carried out through FRX, TG/DTG and XRD analysis of the calcined material at different temperatures and non-calcined, in percentages combined between the commercial and alternative source. As well as proceeded the synthesis of HAPRCal800 using 100% of the residue as calcium source. It can thus be observed that, among the materials, RCal700 had significant quantities in all analyzes with a majority composition of 78.83% of calcium, which factors corroborate to be the heating range used in subsequent studies. As for the synthesis, it can be observed that the percentages of calcium HAPR were higher than the HAPP, and related to the loss of mass and formation of the phases, both had similar results showing the feasibility of using the residue as a substitute for the commercial source of calcium.
