Typically our manufactured Lanthanum Strontium Managanite has a particle size of 100 - 300 nm range and an x-ray diffraction pattern that matches JCPD#40-1100 for an La0.8Sr0.2MnO3 phase.
Lorad Scientists have developed techniques for manufacturing Lanthanum Strontium Manganite Powders with extremely fine compositional control - see X-ray diffraction patterns below for a range of Lanthanum Strontium ratios produced.
