Measurement of CaO-SiO2-SaCl2 slag density by an improved Archimedean method
In order to optimize the removal of boron during the refining of slag to obtain solar grade silicon, the density of molten slag was measured by an improved Archimedean method within a temperature range from 1073 to 1373 K. It was found that the density of molten slag at 1723 K can be deduce...

| Summary: | In order to optimize the removal of boron during the refining of slag to
obtain solar grade silicon, the density of molten slag was measured by an
improved Archimedean method within a temperature range from 1073 to 1373 K.
It was found that the density of molten slag at 1723 K can be deduced by
linear fitting, and that the slag density decreases with increasing
temperature. However, a reduction in slag density occurs with decreasing CaO
concentration. An increase in the molar volume of slag was also observed with
increasing temperature. |
