چکیده مقاله :
Disclosed is a method of preparing pigmentary chromium oxide nano particles having 50 percent particle size less than about 100 nm. Preparation of nano chromium (III) oxide is investigated by thermal decomposition method. According to the disclosed method, a substantially dry solid composition of potassium dichromate and carbon active is heated in CO2atmosphere to a temperature of about 600ºC for 1hour. Thereafter, the solid Cr2O3product was washed twice with distilled water.
