Oxyfluoride glass ceramics are composed of oxide glass network and RE~(3+)-doped fluoride nanocrystals.

Study on extractionof white carbon from kaolinby microwave catalysis;

Microwave catalysis is an important branch of microwave chemistry,and it is the focus of international research.

In the comparison of microwave catalysis oxidation and thermo catalysis oxidation, the same heating power is used.

The optimum parameters were obtained by investigating the relationships between effect of microwave expansion,quality of apple slices and thickness of the materiel,water content,preparation drying temperature, moisture equilibrium treatment time,the microwave power and time.

Taking dried kelps as raw materials,it is then done with a series of processing course including taking off the fishy smell(use 3 % citric acid solution), flavor treating, pasting with serofluid, frying slightly, microwave expansion(condition: middle-low fire, 1 minutes and 30 seconds , slice width 1.

The effects of starch aging on the microwave expansion were studied and the mechanism of the effects of starch aging was also discussed.

Progress in microwave chemistry research and applications;

In the research of microwave chemistry,the temperature simulation and control of the chemical reacting solution is very important.

New experimental devices with uniform electromagnetic field distribution are needed in the study of microwave chemistry dynamics.
