Hygroscopicity:
Although titanium dioxide is hydrophilic, it is not very hygroscopic, and the rutile type is smaller than the anatase type.
The hygroscopicity of titanium dioxide has a certain relationship with the size of its surface area. The surface area is large and the hygroscopicity is high.
The hygroscopicity of titanium dioxide is also related to surface treatment and properties.
Thermal stability:
Titanium dioxide is a material with good thermal stability, and the general dosage is 0.01% to 0.12%.
