Carbon felt purification is widely used in actual industrial production. At the same time, everyone also found that carbon felt purification has many colors, and different colors have different characteristics and different applications. But carbon felt is a sewage crystal, and the color of carbon felt mainly depends on the loyalty and quantity of impurities in the crystal. The abrasive industry considers light blue to black as black carbon felt; colorless to green as green carbon felt.
There are several explanations for the color of carbon felt. It is generally believed to be caused by the presence of foreign impurities. For example, when boron is introduced in the form of boron carbide, the crystal turns black; when the crystal contains nitrogen, it becomes green.
The appearance color of carbon felt is not only related to the color of the crystal itself, but also related to the interference phenomenon of natural light on the crystal surface. When the thickness of the silicon oxide film on the surface of the carbon felt crystal is different, or the reflection angle of light is different, the color of the surface of the carbon felt crystal is also different. Therefore, it is often seen that carbon felt shows brilliant and colorful colors under natural light.
Of course, in practical applications, carbon felt products of different colors have different characteristics, so the production process will also be different. In the process of use, it is necessary to understand the characteristics of different carbon felt purification in advance.
