Calcium pimelate, calcium azelate and zinc azelate are prepared by alkali neutralization process, and calcium dimer are prepared using double decomposition reaction, the effect of binary carboxylate heat stabilizer on PVC thermal stability is studied adopting Congo red method and toast with heat method.

The results revea1 that calcium polyphosphate is a long chain linear inorganic condensed phosphate with amorphous CPP、γ-CPP and β-CPP three different structures.

A series of porous CS/CPP composites were synthesized with CS(chitosan),CPP(calcium polyphosphate)and Sad(stearic acid)was used as the inducing porous substance by heat-dispersion suspension complex method.

Method Porous calcium polyphosphate (CPP) scaffolds were prepared and its cell toxicity was compared with those of hydroxyapatite and tricalcium phosphate.

Mechanical chemical action to crystal structure of dicalcium silicate;

The hydrating rate of dicalcium silicate is slowly, the remarkably initial strength of red mud h.

It was found that some amount of vanadium could be dissolved in dicalcium silicate,and then precipitated with it.

Calcium dialuminate (CA2) and Calcium hexaluminate (CA6) occur at CaO-Al2O3 system as important compounds.

Calcium pimelate, calcium azelate and zinc azelate are prepared by alkali neutralization process, and calcium dimer are prepared using double decomposition reaction, the effect of binary carboxylate heat stabilizer on PVC thermal stability is studied adopting Congo red method and toast with heat method.
