Catalytic Effect of Sodium Nitrite in Carbothermal Reduction of Barites

Page No. 21-26

The paper reports the effect of sodium nitrite on carbothermal reduction of barites. In practice, in
most industrial reductive operations the extent of reduction seldom exceeds 50 percent. After
admixing the sodium nitrite in matrix the carbothermal reduction of barites has shown encouraging
results. Yields have been found to increase to the order of 57 percent. This may contribute a lot to
the economy of the industry.
