摘要

Inorganic black pigments with thermal barrier characteristics, Ca _(2) Mn _(0.85? x ) Ti _(0.15) Zn _( x ) O _(4? x ) (0 ≤ x ≤ 0.10), were synthesized using a conventional solid-state reaction method in order to improve the blackness without decreasing the near-infrared (NIR) reflectance of a Ca _(2) Mn _(0.85) Ti _(0.15) O _(4) pigment, which was previously reported by our group. The composition was optimized to provide both high blackness and NIR reflection characteristics. As a result, the NIR solar reflectance value ( R _(NIR) ) of Ca _(2) Mn _(0.77) Ti _(0.15) Zn _(0.08) O _(3.92) ( R _(NIR) = 74.6%) became larger than that of Ca _(2) Mn _(0.85) Ti _(0.15) O _(4) ( R _(NIR) = 71.7%), and the black color tone of the former ( L * = 23.2, a * = +2.81, b * = +0.83, C = 2.93) was improved in comparison with that of the latter ( L * = 24.4, a * = +4.30, b * = +2.72, C = 5.09). This improvement is caused by the introduction of strain into the [MnO _(6) ] octahedra and a decrease in the manganese ion concentration. The R _(NIR) value of the Ca _(2) Mn _(0.77) Ti _(0.15) Zn _(0.08) O _(3.92) pigment was also larger than those of the commercially available pigments ( R _(NIR) < 53.0%). Therefore, Ca _(2) Mn _(0.77) Ti _(0.15) Zn _(0.08) O _(3.92) has potential to be an inorganic black pigment for thermal shielding.
