The titanium powder in the titanium coil has the following properties:

1. Relative density

Among the commonly used white pigments, the relative density of titanium dioxide is small. Among the white pigments of the same quality, titanium dioxide has a large surface area and a high pigment volume.

2. Melting point and boiling point

Since the anatase type transforms into a rutile type at high temperatures, the melting point and boiling point of anatase titanium dioxide do not actually exist. Only rutile titanium dioxide has a melting point and boiling point. The melting point of rutile titanium dioxide is 1850 ° C, the melting point in air is (1830 ± 15) ° C, and the melting point in oxygen-rich is 1879 ° C. The melting point is related to the purity of titanium dioxide. The boiling point of rutile titanium hydrogenate powder is (3200±300)°C, and titanium dioxide is slightly volatile at this high temperature.

3. Dielectric constant

Titanium dioxide has excellent electrical properties due to its high dielectric constant. When determining some physical properties of titanium dioxide, the crystallographic direction of titanium dioxide crystals should be considered. The dielectric constant of anatase titanium dioxide is relatively low, only 48.

4. Conductivity

The titanium powder in the titanium coil has the properties of a semiconductor, its electrical conductivity increases rapidly with the increase of temperature, and it is also quite sensitive to less oxygen. The dielectric constant and semiconductor properties of rutile titanium dioxide are very important to the electronics industry, and these properties can be used to produce electronic components such as ceramic capacitors.

5. Hardness

According to the Mohs hardness scale of 10 points, the rutile type titanium dioxide is 6-6.5, and the anatase type titanium dioxide is 5.5-6.0. Therefore, in the chemical fiber extinction, the anatase type is used to prevent the wear of the spinneret holes.

The titanium coil is mainly used for heating and cooling the container, and its fixing methods are divided into two types: detachable and non-detachable, which depends on the medium of the material and the corrosion of the titanium tube, but in the design, it is mainly detachable. It is mainly based on the type, which is convenient for the maintenance and cleaning of the titanium tube.
