Rutile titanium dioxide and anatase titanium dioxide are two important types of titanium dioxide, but because of their different properties, they also lead to differences in various aspects, detailing the difference between them.
Titanium dioxide (titanium dioxide) is chemically stable and generally does not react with most substances. There are three crystals of titanium dioxide in nature: titanium plate, anatase titanium dioxide and rutile titanium dioxide. The plate titanium type is an unstable crystal form, and has no industrial use value. Anatase is abbreviated as A type, and rutile type titanium dioxide (Rutile) is abbreviated as R type, which has a stable crystal lattice and is an important white color. Pigments and porcelain glazes have superior whiteness, tinting strength, hiding power, weather resistance, heat resistance, and chemical stability compared to other white pigments, especially innocuous.
Anatase titanium dioxide, ie type A titanium dioxide. It is an excellent white powder pigment with good light scattering ability, so it has good whiteness, strong hiding power, high chemical stability, harmless and odorless, no irritating effect on human body, and it is used in many industrial fields. Such as paint, plastic, paper and ink.
Rutile titanium dioxide, that is, R-type titanium dioxide. Combining the experience of quality control of rutile titanium dioxide production with sulfuric acid method, innovative research on inorganic coating, organic treatment, salt treatment, calcination control, hydrolysis and product application, using advanced hue and particle size control, zirconium silicon aluminum phosphate A new generation of high-grade general-purpose (water-repellent) rutile titanium dioxide developed by a multi-component inorganic coating and a new organic treatment technology. Applicable to a variety of architectural coatings, industrial paints, anti-corrosive paints, inks, powder coatings and other industries.
Rutile titanium dioxide and anatase titanium dioxide are two important types of titanium dioxide. They are said to be two important types of titanium dioxide. This is because rutile titanium dioxide and anatase titanium dioxide are currently on the market. A very wide range of two titanium dioxide series, but because of the different nature of the two, which also led to their differences in various aspects, the following list shows the difference between rutile titanium dioxide and anatase titanium dioxide:
1) Internal structure crystal
Titanium dioxide has three different crystal structures, namely, rutile titanium dioxide, anatase titanium dioxide, and titanium titanium dioxide, which are different in crystal structure. The crystal structure of rutile titanium dioxide is very stable. The titanium-titanium dioxide has very little use, which is mainly due to the instability of its internal structure crystals, so there is no way to preserve it in the long-term and stable state in nature;
2) Melting point and boiling point
Since the anatase type is converted to a rutile type at a high temperature, the melting point and boiling point of the anatase type titanium dioxide are practically absent. Only the rutile type titanium dioxide has a melting point and a boiling point, the rutile type titanium dioxide has a melting point of 1850, the air has a melting point of (1830±15), and the oxygen-rich melting point is 1879. The melting point is related to the purity of the titanium dioxide. The rutile type titanium dioxide has a boiling point of (3200±300), and the titanium dioxide is slightly volatile at this high temperature;
3) Dielectric constant
Since titanium dioxide has a high dielectric constant, it has excellent electrical properties. In determining the physical properties of titanium dioxide, the crystallographic orientation of the titanium dioxide crystals is considered. The dielectric constant of anatase titanium dioxide is relatively low, only 48.
4) Conductivity
Titanium dioxide has the properties of a semiconductor, its electrical conductivity increases rapidly with increasing temperature, and is also very sensitive to hypoxia. The dielectric constant and semiconductor properties of rutile titanium dioxide are very important to the electronics industry, and can be used to produce electronic components such as ceramic capacitors.
5) Hardness
According to the Mohs hardness, the rutile type titanium dioxide is 6 to 6.5, and the anatase type titanium dioxide is 5.5 to 6.0. Therefore, an anatase type is used in the chemical fiber extinction to avoid abrasion of the spinning holes.
