In this work the synthesis of calcium manganite was optimised through a number of different methods of synthesis: mechanochemical, manual homogenisation, Pechini and modified Pechini method. To achieve crystalline calcium manganite synthesised samples were annealed on temperatures from 400 °C to 1200 °C. Synthesised powder samples were characterised with X-ray diffraction analysis, infrared spectroscopy, differential scanning calorimetry and thermogravimteric analysis. Morphology of the powders synthesized by Pechini methods and manual homogenisation was observed by scanning electron microscope (SEM), and the particle distribution and specific surface area were determined. The manual homogenisation method was proven as the most efficient for fast, easy and simple synthesis of calcium manganite. Powder synthesised by this method was further used for drop-castings from suspensions and pulsed laser deposition (PLD) for creating thin films. Suspensions were made with powders annealed at 900 °C, ethanol suspensions were the most stable for the longest time. Particle size of powders was too great to produce fine homogeneous films. Targets for laser ablation were obtained by compaction of powders annealed at 900 °C into tablets. Tablets were annealed at 900 and 1200 °C and their surface and fracture morphology was characterized with SEM. Tablets annealed at 900 °C showed low state of sintering and high brittleness, while tablets annealed at 1200 °C had high state of sintering and were strong enough to be used as targets for PLD. Higher state of porosity was represented in tablets made from non-calcined powders due to release of CO2 and moisture during the process of sintering. These tablets also had larger crystal grains.
