  Ceramic $BiFeO_{3}$ samples were prepared by rapid sintering at $880^OC$. Two
compositions were examined. A $56/44\ Bi_{2}O_{3}/Fe_{2}O_{3}\ mole\%$
composition and a $56Bi_{2}O_{3}\cdot44Fe_{2}O_{3}+6.5wt\%\,NaCl$ composition.
The samples were heat treated at different times up to $8$ minutes and the
phase content was examined as a function of the time using XRD measurements and
analysis. It was demonstrated that using both compositions, maximum $BiFeO_{3}$
phase content is obtained after $3.5$ minutes. In the former approximately
$50\%$ of the material transformed to $BiFeO_{3}$ while in the latter $98.5\%$.
