摘要：
The present invention proposes a method for producing polygonic Zinc oxide platelets having a median specific surface area of more than 25 square meters per gram, in controlled size and morphology, the method comprising: preparing a medium including Zn or its compounds at a concentration within the range between 1.55 and 7.75 moles of Zn/L, in a medium suitable to substitute Zn ions by releasing free protons thereby forming a complex structure including Zn； agitation of the medium in a vessel at a temperature within the range between 50 and 320°C for a duration up to 10 hours to obtain a suspension； filtering the suspension to obtain a filtrate including solid particles； drying and then calcination of the dried filtrate； wherein the agitation is performed with one or more radial flow impellers so that the Reynolds' number in the vessel is higher than 2500 and lower than 10000. The present invention further proposes a product including such platelets.
