Sol-Gel Combustion Synthesis of Silica/ Carbon Black Pigment

Abstract:

A green silicon-containing carbon black pigment was synthesized via a sol-geo combustion technique using TEOS and black ink as raw materials. The obtained black pigment was characterized by XRD, TEM and UV-vis absorption spectrophotometer. The results show that the silicon coated with carbon black pigment can be formed at pH ≥ 2 and the black pigment does not change its color after calcinations at 1300 °C in air implying the carbon black is coated completely with SiO2. When pH is 4, the properties of as-prepared sample are similar with the conventional high-temperature pigment. XRD and SEM further confirm that silicon coats with carbon black fully. The silica/ carbon black pigment may represent an opportunity for the applications in the decoration of the high-temperature ceramic.
