Effect of cold isostatic pressing on the synthesis and particle size of lanthanum manganate

Abstract

X-ray diffraction and thermogravimetry are used to examine the influence of temperature and cold isostatic pressing on the synthesis and crystalline growth of lanthanum manganate. Coprecipitated La_0,7Мn_1,30_3±Δ samples compacted under different pressures before synthesis are examined. It is shown that pressing promotes synthesis, decreases its temperature, and retards crystalline growth. The results demonstrate that cold isostatic pressing is promis-ing for obtaining nanocrystalline manganates
