Introduction of Anatase Ink Titanium Dioxide

Anatase Ink Titanium Dioxide, also known as rutile titanium dioxide, is a titanium dioxide product with a specific crystal form. The following is a detailed introduction to it:

I. Basic information

English name: Anatase Titanium Dioxide

Molecular formula: TiO2

Relative molecular mass: about 79.90 (or 79.87, slightly different depending on the calculation method)

II. Physical properties

Crystal form: Anatase type and rutile type are the two main stable crystal forms of titanium dioxide in nature.

Appearance: Usually appears as a white powder, slightly whiter than rutile type.

Texture: Softer than rutile titanium dioxide.

Refractive index: Lower than rutile titanium dioxide.

Light scattering: Its light scattering performance is also relatively low.

III. Chemical properties

Stability: The chemical properties are stable and generally do not react with most substances.

Solubility: Insoluble in water and organic solvents, but slowly soluble in hydrofluoric acid and hot concentrated sulfuric acid.

IV. Application fields

Due to its unique physical and chemical properties, anatase titanium dioxide has a wide range of applications in many fields:

Ink industry: It is an indispensable white pigment in high-grade inks. Inks containing anatase titanium dioxide are durable and do not change color, have good surface wettability, and are easy to disperse.

Textile and chemical fiber industry: It is mainly used as a matting agent. Since anatase is softer than golden red, it is more suitable for this purpose.

Enamel and ceramic industry: Anatase titanium dioxide has the characteristics of high purity, good whiteness, bright color, and uniform particle size, which can significantly improve the quality and performance of enamel and ceramic products.

Cosmetic industry: Because it is non-toxic and has good hiding power and whiteness, it is widely used in cosmetics such as perfume powder, gouache and cold cream.

Other industries: It is also widely used in coatings, plastics, papermaking, printing inks, rubber, metallurgy and aerospace industries.

V. Preparation and extraction

The preparation of anatase titanium dioxide usually involves complex chemical processes, including extraction from titanium ore, purification, and specific crystal form control. With the advancement of science and technology and the improvement of environmental protection requirements, the preparation process is also constantly being optimized and improved.
