Investigation of the Saturated Vapor Pressure of Zinc, Selenium, and Zinc Selenide

Abstract

Temperature dependences of the saturated vapor pressure of elemental zinc (873-1234 K) and selenium (730-1063 K), as well as zinc selenide (673-1373 K), are investigated using the gravimetric method. Analysis of the experimental data demonstrates that these dependences can be adequately described by equations of the form log P = -A / T + B . The saturated vapor pressures calculated for zinc from the data obtained with the developed gravimetric method are in good agreement with those available in the literature.

Crystal growth of Cu2ZnSnS4 solar cell absorber by chemical vapor transport with I2

“…Despite the low heating rate employed, the pre-treatment of the source material caused the Zn to be partially lost, owing probably to the large volume of the ampoule employed (same dimensions as for the crystal growth) [42]. Interestingly, under the growth conditions of experiment No.…”

Extraction Factor Of Tungsten Sources From Tungsten Scraps By Zinc Decomposition Process

“…The graphite crucible inside the electric furnace was a sealed structure, so that the zinc volatilization could not escape outside the reaction crucible. This zinc volatilization pressure increases inside the reaction crucible as reaction temperature increases [14]. The high zinc volatilization pressure is thought as zinc melting alloy promoting penetration into the tungsten scraps.…”

Investigation of the saturated vapor pressure of selenium and indium sesquiselenide In0.4Se0.6

“…The saturated vapor pressure was measured on a setup graded-up as compared to that used in our previous works [7,8] (Fig. 1).…”

“…However, the use of this method has not received wide acceptance because of the design imperfection of the currently available equipment. This method was further improved in our previous works [7,8]. The experimental setup developed in [7,8] consists of a balance with an opening and a balance beam to which a measuring vessel with a side flask containing a substance to be studied is attached with a holder.…”
