摘要
10。摘要:采用水化学离子交换树脂法制备了一种已知的三磷酸镍钠NiNa 3p3o10·12h2o，并对其进行了x射线衍射、热分析(TGA-DTA)和红外光谱分析，得到了三磷酸p3o105 -的特征谱带。该化合物在不同温度下加热的结果表明，NiNa 3p3o10·12h2o脱水后分解为无定形化合物，在700℃下结晶生成新型三磷酸盐NiNa 3p3o10。NiNa 3p3o10在空间群P - 31 c, Z = 2的六角形体系中结晶，其晶胞尺寸如下:a = b = 13.310(5) Å， c = 9.551(8) Å， M (20) = 80, F (20) = 93 (0.0028);77)， V = 1465.58(0) Å在熔点为744℃之前，尼娜3p3o10是稳定的。首次采用Ozawa和KAS两种不同的方法研究了三磷酸p3o10的热行为动力学。在此基础上，测定并讨论了NiNa 3p3o10·12h2o脱水的动力学和热力学特性以及脱水过程中的热现象

Abstract: A nickel-sodium triphosphate NiNa 3 P 3 O 10 ·12H 2 O already known has been prepared by the method of ion exchange resin of aqueous chemistry and studied by X-Ray diffraction, thermal analyses (TGA-DTA) and infrared spectrometry which show the characteristic bands of a triphosphate P 3 O 105- . The results of the compound heated at different temperatures showed that, after dehydration, NiNa 3 P 3 O 10 ·12H 2 O decomposes into an amorphous compound, then it crystallizes at 700 °C in order to give the new triphosphate NiNa 3 P 3 O 10 . NiNa 3 P 3 O 10 crystallizes in the hexagonal system, space group P - 3 1 c , Z = 2 with the following unit-cell dimensions: a = b = 13.310(5) Å, c = 9.551(8) Å, M (20) = 80, F (20) = 93 (0.0028; 77) and V = 1465.58(0) Å 3 . NiNa 3 P 3 O 10 is stable until its melting point at 744 °C. Two different methods Ozawa and KAS have been selected in studying the kinetics of thermal behavior of the triphosphate P 3 O 10 for the first time. The kinetic and thermodynamic characteristics of the dehydration of NiNa 3 P 3 O 10 ·12H 2 O and the thermal phenomena accompanying this dehydration were determinated and discussed on the basis of the proposed
