Other Experimental

Apart from poor fastness toward alkalies, its general fastness is good.;Primary particle size is less than 20 nm with a specific surface area of 100 square meters/gram.;Iron blue pigments are thermally stable for short periods at temperatures up to 180 °C...The powdered material presents an explosion hazard, the ignition point is 600-625 °C...The pigments are combustible in powder form, ignition in air being possible above 140 °C.;MW: 859.3 Daltons. Powder ranges from uniformly fine, dark granules to course light and dark-colored granules. The crystal structure of Prussian blue is a cubic lattice with the Fe(II) and Fe(III) atoms occupying the corners of the cube and the cyanide groups positioned on the sides./Prussian blue insoluble capsules/;Prussian blue insoluble may not bind to all radioactive elements and some radioactive elements may not undergo enterohepatic circulation, which is needed for Prussian blue insoluble binding and elimination.
