摘要：

The formation conditions of residual carbon have been studied for thermolysis in an inert atmosphere of double complex compounds of two groups of analogs: [Co(A)(6)][Fe(CN)(6)] and [Co(A)(6)](4)[Fe(CN)(6)](3)center dot nH(2)O, where A = NH3, en/2. Isothermal experiments were carried out for extreme points of thermograms to obtain and analyze thermolysis products. Carbon was extracted from thermolysis products by leaching with hydrochloric acid, and its composition, thermal stability in air, specific surface area, and crystalline modification were investigated. The maximum carbon yield was for the compound [Co(NH3)(6)][Fe(CN)(6)], the largest specific surface area of carbon was 380 m(2)/g for [Co(en)(3)][Fe(CN)(6)]center dot 2H(2)O. The extracted carbon contains the admixtures of Co and Fe. The extracted carbon is stable when heated in air up to 450-500 degrees C and burns completely up to 700 degrees C. The carbon samples are largely graphitized.
