In this study, hydroxyapatite-based bone adhesive was prepared by solid-liquid blended crosslinking followed by heating. The prepared bone adhesive has two components: (i) is a mineral composed of calcined dolomite and montmorillonite and (ii) is organic composite composed of citric acid and gelatine. The optimum solid-liquid ratio (0.50 g/mL) of the bone adhesive was determined based on the bond strength of nano-hydroxyapatite/calcined dolomite/citric acid/gelatin system. The best physicochemical properties of the bond adhesive were obtained when the composition of the bone adhesive was as follows: 20 wt% citric acid, 17 wt% gelatin and 12 wt% calcined dolomite. The acquired curing time of bone adhesive was 10.5 min, comparable to the necessity for surgery (5–30 min); moreover, the adhesive strength and compressive strength of the bone adhesive were 12.18 MPa and 9.36 MPa respectively, obtained after being placed in the air for 168 h; besides, the porosity (16.8 %) was found quite suitable. Upon this, a certain amount of montmorillonite was added with calcined dolomite to prepare bone adhesive, resulting reduction in the adhesive strength (10.19 MPa) and compressive strength (7.109 MPa), but improved the biocompatibility of the system. The absorbency of the hydroxyapatite-based bone adhesives in deionized water and Tris-HCl buffer solution was found to be 27.19 % and 18.68 %, respectively, ascertaining that such bone adhesives are efficient in absorbing certain blood and tissue fluid in the biological body and promoting the absorption of required nutrients in the process of bone repair. In addition, the formation of osteoid apatite in the In-vitro study, proved by FTIR and EDAX analysis, rationalized for improving the osteogenic activity. Furthermore, after 56 days of immersion in the Tris-HCl buffer solution, the weight loss rate of the bone adhesive reached up to 42.73 %, indicating that the bone adhesive had satisfactory degradation performance.
