Effect of Strontium Dopant on Electrical Conductivity of Perovskites
The compounds, lanthanium chromite, lanthanium magnetite and lanthanium ferric oxide were prepared through sol-gel methods in powdered form, then calcinated, peletized, and sintered at various temperatures. Electrical conductivity of these compounds was measured at various temperatures. The effectiveness of strontium as a dopant on electrical conductivity was also investigated. Electrical condu...

متن کاملHigh - temperature oxygen non - stoichiometry , conductivity and structure in strontium - rich nickelates
Oxygen nonstoichiometry, electrical conductivity and thermal expansion of La2-xSrxNiO4- phases with high levels of strontium substitution (1 ≤ x ≤ 1.4) have been investigated in air and oxygen atmosphere in the temperature range 20-1050 °C. These phases retain the K2NiF4-type structure of La2NiO4 (tetragonal, space group I4/mmm). The oxygen vacancy fraction was determined independently from th...
متن کاملOn the Loss of Hydraulic Permeability in Ceramic Membranes
to either aluminum ions or surface hydroxyls and can result in the formation of a surface alkoxide. The properties of inorganic membranes are dependent on the The purpose of this note is to illustrate the effects of heat treatment and surface chemistry of the material, which in turn are affected by chemisorption of organic molecules on the permeability characteristics of parameters such as temp...
