What are the differences between titanium dioxide and nano zinc oxide?

There are significant differences between nano titanium dioxide and titanium dioxide in many aspects, and the following will be elaborated from several main aspects:

Physical properties and structure:
나노 이산화 티타늄: It is a white loose powder with a diameter of less than 100 nanometers, which mainly has two crystal forms of Anatase and Rutile. Anatase type has higher reflectivity than rutile type in the short wavelength of visible light, with blue tint, and lower absorption capacity of ultraviolet light, and higher photocatalytic activity.
이산화: commonly known as titanium dioxide, is a white inorganic pigment, with non-toxic, the best opacity, the best whiteness and brightness. Its physical properties include low relative density, high melting point and boiling point, high dielectric constant and high hardness. Titanium dioxide is also divided into anatase type and rutile type.

Chemical properties and stability:
나노 이산화 티타늄: has high chemical and thermal stability, at the same time has super hydrophilic and non-migratory. 또한, nano-titanium dioxide has a long-term bactericidal function under the action of ultraviolet light in the light.
이산화: stable in nature and not easy to change chemically, but it may undergo crystal transformation under certain specific conditions, such as anatase at high temperature will be transformed into rutile.
Scope of application:
나노 이산화 티타늄: due to its excellent UV shielding, antibacterial properties and photocatalytic activity, it is widely used in anti-ultraviolet materials, 섬유, photocatalytic catalysts, self-cleaning glass, sunscreen, 페인트, ink, food packaging materials, paper industry, aerospace industry and lithium batteries and other fields.
이산화: Because of its excellent white pigment properties, widely used in coatings, 플라스틱, 종이, printing ink, chemical fiber, 고무, cosmetics and other industries. 또한, it is also used in the manufacture of refractory glass, 유약, 법랑, 찰흙, high temperature resistant experimental vessels, 등.

Preparation method and cost:
Nanometer titanium dioxide preparation methods are varied, including physical method and chemical method, of which physical method requires higher crushing equipment, and chemical law includes gas phase method, liquid phase method and solid phase method and other methods.

The production process of titanium dioxide is mainly sulfuric acid method and chlorination method, and its cost and production efficiency are different due to the different process and raw materials.
요약, there are obvious differences between nano titanium dioxide and titanium dioxide in physical properties, chemical properties, application range and preparation methods. In practical applications, appropriate materials should be selected according to specific needs.
