Abstract

The possibility of synthesizing manganese-willemite ceramic pigments in the system xMnO · (2 – x)ZnO · SiO2 (x = 0.125; 0.250; 0.375; 0.500; 0.625; 0.750; 0.875 and 1.00) was studied. Manganese-willemite ceramic pigments were synthesized at 800 – 1200°C. The obtained pigments were investigated by means of x-ray phase analysis, electron paramagnetic resonance, and infrared spectroscopy. A Tintometer RT 100 Lovibond reflective colorimeter was used to determine the color characteristics.
