Optical properties of traditional ceramic with different sintering temperatures in terahertz range

Terahertz spectroscopy was used to study the sintering process of traditional ceramic by scanning sample with different final temperatures (from 100-1450°C). Absorption coefficient (α) and refractive index (n) were obtained with different final temperatures. The sintering process was divided into four stages on the basis of α and n, which characterized the ceramic sintering process well. The results coincide with the actual situation. Therefore, THz-TDS represents a promising technique to monitor the synthesis process of materials.
