Process for the preparation of lithium stanates doped with transition metal cations

摘要

A process for the preparation of ceramic material Lithium stannate doped with a transition metal for a humidity sensor mixes a salt of Lithium with SnO2 in dry condition, thereafter mixes in wet conditions using an organic solvent, adds a transition metal compound to the resulting mixture, mixes the mixture thoroughly, drys and compacts the mixture in the range of 5000 to 8000 lbs and heats the pellets so formed at a temperature in the range of 600 DEG to 800 DEG C. for a period in the range of 6 to 12 hours followed by slow cooling to room temperature.
