A simple estimation method for molar Gibbs free energy and enthalpy of formation for complex oxysalt minerals is proposed. Complex oxysalt minerals are divided into complex oxysalt minerals with water and complex oxysalt minerals without water. Complex oxysalt minerals without water can be considered as the composite of acidic oxides and alkaline oxides, so their molar Gibbs free energy or molar enthalpy of formation can be calculated by the summation of molar Gibbs free energy or molar enthalpy of formation of the acidic oxides and alkaline oxides which are combined into the complex compounds.

Results:(1) CBC possesses a natural trabecular structure. Its components is similar to the mineral of bone.(2) CBC has great cellur biocompatibility. It can promote cell adhesion, proliferation and secretory while needn t modification.(3) In nude mice, the ectopic osteogenesis of MCCAB was obvious which was better than that of CBC alone and the new bone formation increased in pace with time. In the MCCAB, both intramembranous and cartilaginous osteogeneses were seen but the former dominated.(4) When MCCAB was autotransplanted intramuscularly, the osteogenesis was much better than that of negative control groups.(5) The MCCAB can repair autogenous calvaria defects effectively and the effect was much better than that of CBM alone and blank group. Conclusion:(1) CBC possesses good biocompatibility, osteoconduction and porous structure, can be used as scaffold material for constructing of tissue engineering bone.
