Lithium is heated in a nitrogen atmosphere

WebVerified by Toppr. Lithium on heating in air forms mainly Li 2O (oxide) and not peroxide (Li 2O 2). Li + being smaller in size cannot stabilize larger anion as O 22− (peroxide). Thus, … WebThermogravimetric analysis was performed at different heating rates to the temperature of 750 °C. The main pyrolytic decomposition step was observed in the temperature range of 248−500 °C. In the fixed-bed reactor, waste sludge was pyrolyzed at 450 and 600 °C in a nitrogen atmosphere. Pyrolysis products were separated as gas, liquid, and char.
