US Patent 6416868,  Alkaline earth-manganese oxide pigments

PDF文档

碱土锰氧化物被用作颜料。碱土锰氧化物颜料是最好的配方MexMnOy，至少有一个由金属钙，锶，钡，镁等元素，x是从0.01到0.99，而y是大于或等于x+1和小于或等于x+2。颜料可以作为着色剂，也有增强的反射特性，特别是在红外区，并可以降低红外热积聚。这些着色剂可以加入如油漆，油墨，塑料，玻璃，陶瓷及类似材料，用于物体着色或涂料应用。该专利还涵盖了这些颜料的生产。

Alkaline earth-manganese oxides are used as pigments. The alkaline earth-manganese oxide pigments are preferably of the formula Me_xMnO_y, where Me is at least one metal selected from Ca, Sr, Ba and Mg, x is from 0.01 to 0.99, and y is greater than or equal to x+1 and less than or equal to x+2. The pigments are useful as colorants, and also possess improved reflectance characteristics, particularly in the IR region, and may reduce IR-induced heat buildup. These colorants can be used to form colored objects, or coat objects when they are either added into or applied onto materials such as paints, inks, plastics, glasses, ceramics and the like. The patent also covers the production of these pigments.
