Performance Testing of Black Oxide Nanoparticle Pigment for High Temperature Coating Application

Manufacture of pigments as high temperature resistant paint is obtained through the mechanical alloying process between manganese ore (MnO2) with hematite (Fe2O3) for 10 hours, 20 hours and 30 hours using a ball mill alumina. Milled powders were calcined 1000oC to obtain manganese ferrite pigments. Pigment was compared with commercial manganese pigment (imported) by formulated into paints and high temperature resistant tested by varying the temperature of 200oC, 400oC, and 600oC. Analysis of calcined powder using XRD, while color changing after burning test using the CIE-L*a*b system. XRD characterization results on samples of synthetic pigment indicate a pattern MnFe2O4, MnFeO3 and Fe3O4. High Temperature testing results on synthetic and commercial pigment, both of them have the capacity to withstand. This shows that, the synthetic pigment may replace imports / commercial pigment.
