    Metal Paint
In summary, the metal oxide commonly used in white paint is titanium dioxide (TiO2). It is added to produce a bright white color due to its high refractive index. Titanium dioxide is generally safe to use in paint, but caution should be taken when handling the powdered form. Besides its brightening properties, it also helps to increase the durability and weather resistance of paint. Other metal oxides, such as zinc oxide and iron oxide, may also be used in paint for different purposes.

I'll give you a .5 point on that. I'm looking for something else that makes bright white paint.

1. What is the metal oxide used in white paint?

The metal oxide commonly used in white paint is titanium dioxide (TiO2).

2. Why is this metal oxide added to paint?

This metal oxide is added to paint to make it bright white, as it has a high refractive index which reflects light, creating a bright and opaque finish.

3. Is titanium dioxide safe to use in paint?

Yes, titanium dioxide is generally considered safe to use in paint as it is non-toxic and non-reactive with other chemicals. However, care should be taken when handling the powdered form to avoid inhalation.

4. Are there any other benefits of using titanium dioxide in paint?

Aside from its brightening properties, titanium dioxide also helps to increase the durability and weather resistance of paint, making it a popular choice for exterior applications.

5. Is titanium dioxide the only metal oxide used in paint?

No, there are other metal oxides that may be used in paint for different purposes. For example, zinc oxide is sometimes added to improve the adhesive properties of paint, while iron oxide can be used as a pigment to create different shades of paint.
