Calcium stones are most commonly occurring form of cholelithiasis or gallbladder stones most one of the oldest and common afflictions of humans. Calcium phosphate is dissolved minerals in causes of renal to gallbladder stone in both human and animals. Of course, the calcium phosphate is one of the components of gallbladder. Calcium phosphate doped with (Cu and Mg) are crystals are grown by sol-gel method. In the present work the growth and characterization of pure and doped with (Cu and Mg) crystals. The grown crystals were characterization by FT-IR, SEM-EDX and TG/DTA analysis.

Amorphous calcium phosphate (ACP) was prepared by a sol-gel method from Ca alkoxide synthesized with Ca metal and ethanol in N2 atmosphere. As-prepared products by sol-gel method were spherical ACP particles of approximately 3 to 10 nm in diameter before heat-treatments. The results from Ca-K edge of as-synthesized ACP showed only one peak around 0.2 nm, suggesting the presence of the first neighbor of Ca in Ca-PO4 cluster.

Mullite Fibers

Composite sol with spinnability was prepared from an aqueous solution using polyvinyl butyral (PVB), Al (NO3)3·9H2O (AN) and tetraethylorthosilicate (TEOS) via non-hydrolytic sol-gel method. The mullite fibers with good flexibility were also obtained. The viscosity of composite sol increased with the increasing PVB content, water-bathing temperature and aging time. FTIR spectroscopy of composite gel showed a new absorption peak due to the C=O group, which implied the presence of new reaction product. It could be explained by the reaction among PVB, AN and TEOS.
