Product Description
Titanium dioxide is an important inorganic chemical pigment, mainly composed of titanium dioxide. There are two production processes for titanium dioxide: sulfuric acid method and chlorination method. It has important applications in industries such as coatings, ink, papermaking, plastic rubber, chemical fiber, ceramics, etc
Physical characteristics
1. Relative density
Among commonly used white pigments, titanium dioxide has the smallest relative density, while among white pigments of the same quality, titanium dioxide has the largest surface area and the highest pigment volume.
2. Melting point and boiling point
Due to the fact that anatase titanium dioxide transforms into rutile type at high temperatures, the melting and boiling points of anatase titanium dioxide do not actually exist. Only rutile type titanium dioxide has a melting point and boiling point. The melting point of rutile type titanium dioxide is 1850 ºC, the melting point in air is (1830 ± 15) ºC, and the melting point in oxygen rich is 1879 ºC. The melting point is related to the purity of titanium dioxide. The boiling point of rutile type titanium dioxide is (3200 ± 300) ºC, and at this high temperature, titanium dioxide is slightly volatile.
3. Dielectric constant
Due to its high dielectric constant, titanium dioxide has excellent electrical properties. When determining certain physical properties of titanium dioxide, it is necessary to consider the crystallization direction of titanium dioxide crystals. The dielectric constant of anatase titanium dioxide is relatively low, only 48.
4. Conductivity
Titanium dioxide has the properties of a semiconductor, its conductivity rapidly increases with temperature, and it is also very sensitive to hypoxia. The dielectric constant and semiconductor properties of rutile type titanium dioxide are very important for the electronic industry, and can be used to produce electronic components such as ceramic capacitors.
5. Hardness
According to the Mohs hardness scale, the rutile type titanium dioxide is 6-6.5, and the anatase type titanium dioxide is 5.5-6.0. Therefore, in chemical fiber extinction, the anatase type is used to avoid abrasion of the spinneret hole.
6. Hygroscopicity
Although titanium dioxide has hydrophilicity, its hygroscopicity is not very strong, and the rutile type is smaller than the anatase type. The hygroscopicity of titanium dioxide is related to its surface area, which is large and has high hygroscopicity. It is also related to surface treatment and properties.
7. Thermal stability
Titanium dioxide is a substance with good thermal stability.
8. Particle size
The particle size distribution of titanium dioxide powder is a comprehensive indicator that seriously affects the performance of titanium dioxide pigments and product applications. Therefore, discussions on covering power and dispersibility can be directly analyzed from the particle size distribution.
The factors that affect the particle size distribution of titanium dioxide powder are relatively complex. Firstly, the size of the original hydrolysis particle size is controlled and adjusted by the hydrolysis process conditions to keep the original particle size within a certain range. Next is the calcination temperature. During the calcination process of metatitanic acid, the particles undergo a phase transition and growth period. Control the appropriate temperature to keep the growing particles within a certain range. Finally, the crushing of the product is usually achieved by modifying the Raymond mill and adjusting the analyzer speed to control the crushing quality. Other crushing equipment can also be used, such as universal mills, airflow crushers, and hammer grinding devices.
