CaCO3 (for the silicon nitride containing the mass fraction of CaO w = 10 %) was premixed in the starting reactants depending on the final powder composition and the type and amount of the secondary phases required for sintering. The synthesis was carried out in a tube furnace in different temperature ranges (1400 °C, 1450 °C and 1475 °C for 3h) under a nitrogen-gas atmosphere. Having completed the synthesis process, the powder properties were examined using standard characterization techniques (XRD, SEM,etc.)"},{"@xml:lang":"sl","#text":"V tej študiji so bili sintetizirani s karbotermično redukcijo in nitridacijo z a-fazo bogati prahovi Si3N4 z dodatkom za sintranje (CaO).
