Effect of crystallographic orientation in textured Baa0.92Ca0.08TiO3 piezoelectric materials
Haugen, Astri Bjørnetun; Morozov, Maxim; Johnsson, Mats; Grande, Tor; Einarsrud, Mari-Ann (Journal article; Peer reviewed, 2014)Strongly textured lead-free Ba0.92Ca0.08TiO3 piezoelectric ceramics were fabricated by tape casting and templated grain growth. Dense ceramics with both favorable and unfavorable texture were successfully prepared. Enhanced ... -
Thermal Conductivity of A-site Cation-Deficient La-Substituted SrTiO3 Produced by Spark Plasma Sintering
Loland, Thomas Emdal; Sele, Jaran; Einarsrud, Mari-Ann; Vullum, Per Erik; Johnsson, Mats; Wiik, Kjell (Journal article; Peer reviewed, 2015)During the last decade oxide-based thermoelectric materials have received increased attention due to their high stability and thermal robustness at high temperatures as well as the availability and nontoxic nature of a ... -
Thermoelectric properties of A-site deficient La-doped SrTiO3 at 100–900 °C under reducing conditions
Singh, Sathya Prakash; Kanas, Nikola; Desissa, Temesgen Debelo; Johnsson, Mats; Einarsrud, Mari-Ann; Norby, Truls Eivind; Wiik, Kjell (Journal article; Peer reviewed, 2019)Lanthanum doped strontium titanate is a potential n-type thermoelectric material at moderate and high temperatures. (La0.12Sr0.88)0.95TiO3 ceramics were prepared by two different routes, conventional sintering at 1500 °C ...
