Synthesis and conductivity of Zn2SnO4-based cermet material

SHS synthesis of Zn 2 SnO 4 -based cermet material from Zn + NiO + SnO 2 compacted powder mixtures has been studied. The final product is obtained as a monolithic cylindrical block composed of a ZnO-based outer layer and Zn 2 SnO 4 -based central part, in which the metal phase is distributed. The ph...

Summary:SHS synthesis of Zn 2 SnO 4 -based cermet material from Zn + NiO + SnO 2 compacted powder mixtures has been studied. The final product is obtained as a monolithic cylindrical block composed of a ZnO-based outer layer and Zn 2 SnO 4 -based central part, in which the metal phase is distributed. The phase composition and microstructure of combustion products have been studied by x-ray phase analysis (XPA), electron microscopy, and microprobe techniques. It is established that the structure of the obtained cermet material has a dramatic effect on their conductivity.
