Effect of TiO2.content on the burnability of clinker with high C3. were investigated by determination of free lime in final product, and the clinker phase formation, microstructural features of C3. and the solubility of TiO2.in C3. were further studied by XRD, SEM/EDS analysis. TiO2.accelerates the combination of free lime in the samples, free lime content decreases obviously with TiO2.increasing up to 2. and almost remains above 2.. A new phase cao·TiO2.was found when TiO2.was up to 3., and samples with TiO2.displayed well-formed uniform size hexagonal C3. crystal. The limit of solubility of TiO2.in C3. at 1400 ℃ is about 1.7%.

Samples of the jade artifacts unearthed from the Liangzhu sites at Yuhang (Fanshan,Yaoshan, Huiguanshan and tangshan) of zhejiang province were described. The chemical composition, phase and jade structure of a hundred and more intact samples were analyzed by the non-destructive techniques of PIXE, XRD and laser Raman spectroscopy. Results showed that the minerals of the jade artifacts mostly belonged to tremolite and tremolite-actinolite. Relationship of the civilization development in the Neolithic age and the application of tremolite type mineral in jade artifacts was discussed. The contents of rare and trace elements in tremolite jade artfacts and in mineral samples were measured for the first time. The possible mineral sources of these tremolite type jade artifacts were discussed.
