Synthesis and characterization of cobalt doped green ceramic pigment from tannery sludge

Low temperature synthesis of green submicro Cr‐ZrSiO4 ceramic pigments by solid‐state method

“…For the sake of comparison, the L*, a*, and b* parameters of different green pigments 34‐36 are listed in Table 4. It can be obviously observed that the L*, a*, and b* parameters of pigments prepared in this work are different from that of other green pigments, which shows that pigments in this work have features in the aspect of color.…”

Recycling of chromium wastes from the tanning industry to produce ceramic nanopigments

“…The concentrations revealed the urgent need to implement the concepts of industrial symbiosis in this industrial sector, in order to transform the highly toxic waste into the raw materials of a new process, eliminating any need to store the waste indefinitely. Several studies [72][73][74][75] highlight the negative environmental impact of using landfills, such as leaching of potentially toxic substances to soils and subterranean waters, alteration of the chemical composition of the local vegetation, and accumulation of toxic elements throughout the food chain.…”

Patterns in the synthesis processes and the characteristics of silicate-spinal ceramic pigments when introducing mineralizers

“…In this case, the qualitative indicators of the obtained dyes often are not inferior, and sometimes superior, to the quality of materials synthesized from conventional, technically pure and natural raw components. At the same time, the firing temperature of such pigments remains quite high and is in the interval of 1,200-1,300 °C [5][6][7].…”
