According to the latest search results, the following is the chemical composition comparison between zircon powder and zircon sand:

I. Chemical constituents of zircon powder

ZrO₂ (zirconium dioxide): the content is usually more than 65%, and some high-purity products can reach more than 66%.

SiO₂ (silicon dioxide): the content is about 32%-33.5%.

TiO₂ (titanium dioxide): The content is low, usually less than 0.1%-0.15%.

Fe₂O₃ (ferric oxide): The content is low, usually less than 0.05%-0.1%.

Al₂O₃ (alumina): The content is low, usually less than 0.3%-0.9%.

P₂O₅ (phosphorus pentoxide): the content is low, usually less than 0.5%.

II. Chemical composition of zircon sand

ZrO₂ (zirconium dioxide): The content is usually between 65% and 67%.

SiO₂ (silicon dioxide): the content is about 32%-34%.

TiO₂ (titanium dioxide): The content is low, usually less than 0.1%-0.15%.

Fe₂O₃ (ferric oxide): The content is low, usually less than 0.1%.

Al₂O₃ (alumina): The content is low, usually less than 0.3%.

P₂O₅ (phosphorus pentoxide): the content is low, usually less than 0.5%.

III. Comparative summary of chemical components

Main components: The main components of zircon powder and zircon sand are ZrO and SiO, with ZrO content above 65% and SiO content around 32%-34%.

Impurity content: zircon powder and zircon sand have low impurity content (such as TiO, FeO, Al₂O₃, P₂O₅, etc.), but zircon powder may have slightly higher TiO and FeO content than zircon sand.

Purity difference: The purity of zircon powder may be slightly higher than that of zircon sand, especially in high-purity applications.

To sum up, the chemical composition of zircon powder and zircon sand is basically similar, but there are slight differences in impurity content and purity, and the specific selection should be determined according to the actual application requirements.
