Özet:

 


The main
raw material used in the production of Sr metal and its compounds is SrSO4
(celestite) mineral and Turkey has valuable Sr mineral deposits. One of the
important steps in the production of Sr compounds is the production of
strontium oxalate compound that does not contain alkali compunds as
contamination. Strontium is used as a primary raw material in the production of
oxalate, superconducting material and luminescence. 


In this
study, the in situ conversion of SrSO4 into SrC2O4.H2O
by ammonium oxalate is investigated and the effect of rotation speed, ball /
sample ratio and solution concentration on the conversion reaction has been
determined. It was found that the conversion of SrO4 to SrC2O4.H2O
was increased with the increase in mole ratio of (NH4)2C2O4
to SrSO4. The maximum conversion, above 70 %, was achieved by using
(NH4)2C2O4 / SrSO4 mole
ratio: 1.5, rotation speed: 500 rpm and ball / sample ratio: 13.
