What is the key role of the calcination temperature curve of calcined zinc oxide in the quality of its final product?

Raw zinc materials often contain crystal water, organic impurities and unreacted zinc compounds, and the decomposition temperature ranges of these components are different.

When direct zinc oxide is used in coating formulations, what specific effect does its needle-like structure have on improving suspension performance?

The needle-shaped particles of direct zinc oxide have a large aspect ratio and form a three-dimensional network structure in the coating system.

How does calcined zinc oxide alter the crystal structure of zinc oxide, thereby affecting its fluidity in glazes?

Through high-temperature heat treatment, the physical form and crystal structure of zinc oxide are significantly improved, significantly enhancing its processability and firing stability in ceramic glazes.

How does direct zinc oxide improve the corrosion resistance and weather resistance of coating products?

In terms of anti-corrosion performance, direct zinc oxide can form a dense protective film on the coating surface.

What influence does the specific surface area of calcined zinc oxide have on its catalytic performance, and what catalytic reactions is it suitable for?

The effect of the specific surface area of calcined zinc oxide on the catalytic performance is first reflected in the number of active sites.

How does the activity of direct zinc oxide improve the efficiency of chemical reactions?

The more active direct zinc oxide has more complete contact with the reactants and can participate in the reaction process more quickly, prompting the reaction to proceed quickly in the direction of generating products.
