Hydroxyapatite Ca10 (PO4) 6 (OH) 2 is a calcium compound whose chemical composition is similar to human bone minerals. In this study, hydroxyapatite was formed into a composite material by adding borosilicate (borax and silica). For the formation of this composite material, the Hydroxyapatite borosilicate composition has been adjusted, namely: 90:10, 85:15, 80:20, 75:25, 70:30 wt.%. The samples were made with different compacting forces, namely 5 KN, 15 KN, and 25 KN with a sintering temperature of 800 ° C. 0.003734 gr / mm3. While the lowest density value is found in the composition 75:25 Wt.%, The compacting force is 5 KN with a value of 0.002436 gr / mm3. The decrease in the density value is influenced by the composition and compaction force applied. The greater the borosilicate composition, the lower the density. Meanwhile, the greater the compacting force applied, the density will increase.
