Results indicate that both of barium thioglycolate and barium-natrium thioglycolate can increase the thermal stability of PVC system, and the thermal stability of barium thioglycolate is better.

巯基乙酸钡和巯基乙酸钡-钠都能提高PVC的热,但巯基乙酸钡的要好于巯基乙酸钡-钠。

The IR spectra of hydrogel, alcogel and aerogel of BaFe12O19 were studied, and the ones of the powders calcined at different temperatures for different time were also studied.
