The physiochemical properties showed a lower specific gravity, viscosity index, pH value, flash point and pour point as compared to a conventional castor oil. The flashpoint of TPSF (98 ̊C) shows that it is of very low hazard to the operator and the environment, however, the pour point of TPSF (-1 ̊C) is high compared with -43 ̊C for the castor oil, which makes TPSF only suitable for tropical countries like Nigeria. Performance evaluation of the developed cutting fluid was compared with a conventional castor oil in machining operation on a lathe machine. It was found that both samples have similar cooling properties. The optimized cutting speed in terms of chip thickness, chip thickness ratio and cooling temperature was found to be 127.3 rpm.

The discussion is in relations of the obligatory features vital to attain the best properties for the envisioned bid of bone graft. The process approaches that are capable of fabricating the essential microstructure and the ways to advance the mechanical properties of natural mined HAp are reviewed. The standard values for tensile strength were found to be within the range of 40–300 MPa, compressive strength was 400–900 MPa, while Elastic modulus was 80–120 GPa and fracture toughne...
