摘要
Zinc oxide crystals of modified habits are revealed comprising retained protein particles, in which the said crystals are in disk form and are in the form of medium -sized spherical sets of 0,8 a m to 1,5 a m and where the thickness of each disc is 10 -nm to 3. 0 nm and mean diameter is from 200 nm to 500 nm, where the said protein is soluble in water and where the said protein is at least one of sericin, bovine serum albumin, gelatine, egg albumin, casein, zein,Whey or plain. The process of manufacturing zinc oxide crystals of modified habits is also revealed including the steps of: (i) mixing the aqueous solution of a water -soluble protein with an aqueous solution of a soluble zinc salt in non -hydrolysible water, in which the said protein Is soluble in water and in which the said protein is at least one of sericin, bovine serum albumin, gelatine, egg albumin, casein, zein, whey or smoothy; (ii) addition of a weak base to it; (iii) heating of the step reaction mixture (ii) to reach a temperature D And 60 to 90 (c); and, (iv) filtering the contents of the step (iii),Washing the residue with water and drying it to obtain the said zinc oxide crystals from modified habits as filtered.
