Evaporation characteristics of elemental tellurium in the vacuum distillation process based on differential weight method measurement

Vacuum distillation is an indispensable process in the preparation of high purity tellurium. However, kinetic data of tellurium evaporation such as the actual evaporation rate, critical pressure, and evaporation coefficient have not been reported. In this work, the actual volatilization rate of tell...

520			\|a Vacuum distillation is an indispensable process in the preparation of high purity tellurium. However, kinetic data of tellurium evaporation such as the actual evaporation rate, critical pressure, and evaporation coefficient have not been reported. In this work, the actual volatilization rate of tellurium was measured under different temperature and system pressure conditions. The vacuum volatilization of tellurium was analyzed in detail, which shows that there is a linear relationship between the natural logarithm of tellurium evaporation rate and the reciprocal of temperature, while the system pressure is constant. Additionally, when the distillation temperature is fixed, the tellurium evaporation rate and the system pressure meet the Logistics nonlinear relationship (ω actu = (A1-A2)/[1+(p/p0)a]+A2). Above the melting point of Te, the logarithm of critical pressure is linearly related to the reciprocal of the temperature (lgp crit = 3.26–937.19/T). The experimental maximum evaporation rate of tellurium is calculated by the method of limiting and the evaporation coefficient α is between 0.4 and 10. The present study provides basic evaporation parameters, describes the behavior of tellurium under vacuum distillation, and offers theoretical guidance for vacuum distillation refining of tellurium.

However, kinetic data of tellurium evaporation such as the actual evaporation rate, critical pressure, and evaporation coefficient have not been reported. In this work, the actual volatilization rate of tellurium was measured under different temperature and system pressure conditions. The vacuum volatilization of tellurium was analyzed in detail, which shows that there is a linear relationship between the natural logarithm of tellurium evaporation rate and the reciprocal of temperature, while the system pressure is constant. Additionally, when the distillation temperature is fixed, the tellurium evaporation rate and the system pressure meet the Logistics nonlinear relationship (ω actu = (A1-A2)/[1+(p/p0)a]+A2). Above the melting point of Te, the logarithm of critical pressure is linearly related to the reciprocal of the temperature (lgp crit = 3.26–937.19/T). The experimental maximum evaporation rate of tellurium is calculated by the method of limiting and the evaporation coefficient α is between 0.4 and 10. The present study provides basic evaporation parameters, describes the behavior of tellurium under vacuum distillation, and offers theoretical guidance for vacuum distillation refining of tellurium.

abstract	Vacuum distillation is an indispensable process in the preparation of high purity tellurium. However, kinetic data of tellurium evaporation such as the actual evaporation rate, critical pressure, and evaporation coefficient have not been reported. In this work, the actual volatilization rate of tellurium was measured under different temperature and system pressure conditions. The vacuum volatilization of tellurium was analyzed in detail, which shows that there is a linear relationship between the natural logarithm of tellurium evaporation rate and the reciprocal of temperature, while the system pressure is constant. Additionally, when the distillation temperature is fixed, the tellurium evaporation rate and the system pressure meet the Logistics nonlinear relationship (ω actu = (A1-A2)/[1+(p/p0)a]+A2). Above the melting point of Te, the logarithm of critical pressure is linearly related to the reciprocal of the temperature (lgp crit = 3.26–937.19/T). The experimental maximum evaporation rate of tellurium is calculated by the method of limiting and the evaporation coefficient α is between 0.4 and 10. The present study provides basic evaporation parameters, describes the behavior of tellurium under vacuum distillation, and offers theoretical guidance for vacuum distillation refining of tellurium.
