Recent research on YIn1-xMnxO3 has illustrated the potential to prepare cobalt-free blue ceramic pigments with the colour due to Mn 3+ in trigonal bipyramidal coordination in this compound . The vivid blue colour, low toxicity, and thermal stability have led to this pigment being recently approved for commercial use. The YIn1-xMnxO3 series has also been shown to have excellent near-infrared reflectance and show potential as cool pigments for use to reflect solar heat such as roofing materials . However, the cost associated with indiumbased precursors causes an issue with these compositions.
