通过对小柴旦天然沉积钠硼解石矿物(Na_2O·2CaO·5B_2O_3·16H_2O)的热分析研究确定了热脱水反应的阶段、温度和产物,并由DTA、TG、DTG和DSC确定了钠硼解石脱水、重结晶和熔融的温度,给出了脱水过程的热化学反应方程式及各个脱水阶段产物的X—ray粉末衍射和红外光谱结果。
The thermal dehydration reaction phase, temperature and product were determined by thermal analysis of natural sedimentary soda-boehmite mineral (Na 2 O 2 CaO · 5B 2 O 3 · 16H 2 O) in Xiaochai Dan, and sodium borohydride was determined by DTA, TG, DTG and DSC The dehydration, recrystallization and melting temperature of the stone are given. The thermochemical reaction equations for the dehydration process and X-ray powder diffraction and infrared spectroscopy results for the individual dehydration stages are given.
