.... The most significant one is the lower reduction temperatures ( 850 – 900 ° C for the SnO 2 versus 1100 – 1150 ° C for the ZnO). The rate of carbothermal reduction was studied experimentally. SnO 2 powder (300 mesh, 99.9% purity) was reduced with beech charcoal and graphite using a thermogravimetric...
