Rheology and Printability of Pastes Based on BaTiO3 Nanopowder Depending on Ethyl Cellulose Viscosity

Autor: Umerova, S.O., Dulina, I.O., Ragulya, A.V.

This paper is about rheology of pastes based on BaTiO3 nanopowder with ethyl cellulose 100 cP (paste P1) and 10 cP (paste P2) as organic binder. It was established, that P1 was pseudoplastic – thixotropic system and P2 was rheopexic - pseudoplastic
