| Abstract: | A nanocomposite chrysotile-KDP (KH2PO4) was prepared. KDP was introduced into empty nanochannels of chrysotile asbestos with diameters of ～5 nm. Thermal conductivity κ and heat capacity at a constant pressure C p of the samples of chrysotile asbestos and nanocomposite chrysotile asbestos-KDP were measured in a temperature range of 80–300 K. Based on the analysis of the behavior of temperature dependences κ(T) and C p (T) of the composite, temperatures of the ferroelectric transition T F for KDP in nanochannels of chrysotile asbestos were determined. It turned out to be equal to ～250 K at T F ～ 122 K for massive KDP samples. |
