Abstract: Grey-black inclusion pigments are obtained by enclosing iron titanates of the formula FeTiO3 in zirconium silicate crystals. They are prepared by igniting a mixture of zirconium oxide having a particle size distribution of 6 to 10 mu m and a specific surface area of 2 to 5.2 m /g, silica and iron oxides and titanium oxides or iron compounds and titanium compounds forming oxides in the presence of mineralisers under oxidising conditions at 800 to 1300 DEG C.

Abstract: A zeolite catalyst and a method for reduction of nitrogen oxides present in waste gas streams is described. The method includes mixing the waste gas containing nitrogen oxides with ammonia. At an elevated temperature, this mixture is passed over a zeolite catalyst. Preferably, the zeolite catalyst is in a monolithic or honeycomb form. The zeolite catalyst includes one or more of the following subgroup metals: copper, iron, molybdeum and cerium. The zeolite catalysts made in accordance with this invention show better conversion of nitrogen oxides and longer life than known catalysts.
