Abstract
This project intends to study the effects of SnO2 addition (1%, 2% e 5%), in the varistors properties, into the ceramic CaCu3Ti4O12/CaTiO3 (CCTO/CTO), using two sintering methods: by the conventional furnace and microwave furnace. Ceramic powders will be prepared and they are going to be sintered in a conventional furnace and microwave furnace. These powders will be thermally characterize…
