Dec 06, 2016· A high CaCl2 content in the resulting annealed products with 30% CaCl2 addition delayed the decomposition of CsCaCl3 and thus lowered the Cs vaporization ratio compared to that with 10% CaCl2 addition at 900-1250 °C. Thermal treatment with CaCl2 addition is a proposed method to remove Cs from Cs-contaminated incineration ash.

Pure PVC had the highest height and the C db of pure PVC was the largest, showing that the initial color of pure PVC could be the worst. The smallest was the PVC stabilized with 3 phr of MSE-Al and 1 phr of ZnSt 2 , indiing that PVC stabilized with this component had the best initial color, which was consistent with the results of the
Fig. 4 Effect of calcination time on extraction of Rb (muscovite/ CaCl2/NaCl = 1.00:0.25:0.25; temperature = 850 °C) chlorinated. NaCl/CaCl2 is not completely dissolved and existed in the form of clusters at 750 °C, and the surface of particles become uniform at 850 °C, which can be seen from Fig. 3.

As previously reported, Ti metal was successively subjected to NaOH, CaCl2, heat, and water treatments to form a calcium-deficient calcium titanate layer on its surface. When placed in a simulated body fluid (SBF), this bioactive Ti formed an apatite layer on its surface and tightly bonded to bones in the body.
