Titanium powder in titanium coil has the following characteristics:
1. Relative density of titanium coil
In the commonly used white pigments, the relative density of titanium dioxide is small. Among the white pigments of the same quality, titanium dioxide has large surface area and large pigment volume.
2. Melting point and boiling point
Because anatase will change into rutile at high temperature, the melting point and boiling point of anatase titanium dioxide almost do not exist. Only rutile titanium dioxide has melting point and boiling point. The melting point of rutile titanium dioxide is 1850 ℃, the melting point in air is (1830 ± 15) ℃, and the melting point in oxygen enrichment is 1879 ℃. The melting point is related to the purity of titanium dioxide. The boiling point of rutile titanium dioxide is (3200 ± 300) ℃, and titanium dioxide volatilizes slightly at this high temperature.
3. Dielectric constant of titanium coil
Titanium dioxide has excellent electrical properties because of its high dielectric constant. When determining some physical properties of titanium dioxide, the crystal orientation of titanium dioxide crystal should be considered. The dielectric constant of anatase titanium dioxide is relatively low, only 48
4. Conductivity
Titanium powder in titanium coil has semiconductor properties. Its conductivity increases with the increase of temperature and is also sensitive to oxygen reduction. The dielectric constant and semiconductor properties of rutile titanium dioxide are very important for the electronic industry. It can be used to produce ceramic capacitors and other electronic components.
5. Hardness of titanium coil
Taking Mohs hardness tester for 10 points, rutile titanium dioxide is 6-6,5 and anatase titanium dioxide is 5,5-6,0. Therefore, in chemical fiber matting, sharp spinneret holes are used to prevent wear of titanium dioxide.
Titanium coils are mainly used for heating and cooling containers. The fixing methods are divided into detachable and non detachable. This depends on the medium of the material and the corrosion to the titanium pipe, but the main design is mainly removable, which is convenient for the maintenance and cleaning of the titanium pipe.
