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.

Abstract Calcium and hafnium co-doped barium titanate could be used as a replacement for lead zirconate titanate, which is a lead-based ferroelectric material. Solid state reaction accompanied by the usual sintering technique is the classical ceramic-processing method, which demands a lot of time and effort. The present work aims to make the process a lot easier and quicker by employing a modified sol-gel combustion technique to synthesize polycrystalline Ba0.85Ca0.15Ti(1-x)HfxO3 (x=0.00, 0.05, 0.10, 0.15) electro ceramics . The molar ration is fixed at 1:1 for metal and citric acid at pH ~ 1. It was found that Ba0.85Ca0.15Ti(1-x)HfxO3 (where x=0.00, 0.05, 0.10, 0.15) crystallizes completely at around 1000 °C which is much lower than traditional methods. The structure supposedly displays a tetragonal symmetry with the P4mm space group as confirmed through x-ray diffraction (XRD) and Raman spectroscopy.
