Description
  • The novel two-step synthesis method decreasing the calcining temperature necessary for formation of spinel lattice and as well for reaching of bright and clear hue of the pigments prepared were investigated. This work aims to utilization of DTA for synthesis monitoring. Influence of raw materials and temperature of calcination on color properties were observed. The characterization of the samples was performed by X-ray diffraction and colorimetry in the CIE L*a*b* system. It was proved that the black spinel pigment Cu2.3Mn2.8Cr4.9Ox can be prepared at finally temperature 700°C as one-phase system with high quality black hue.

  • Nový dvoustupňový způsob syntézy, který byl zkoumán, vede ke snížení teploty kalcinace potřebné k formování spinelové mřížky a také k silnějším a čistším barvám anorganických pigmentů. Tato práce se zabývá využitím DTA pro sledování průběhu syntézy. Byl sledován vliv výchozích surovin a teploty kalcinace na optické vlastnosti produktu. Charakterizace produktů byla prováděna rentgen-difrakční analýzou a optické vlastnosti byly hodnoceny v systému CIE L*a*b*. Bylo dokázáno, že černý spinelový pigment Cu2.3Mn2.8Cr4.9Ox je možné připravit jako jednofázový při teplotě 700°C s kvalitním černým odstínem. (cs)
