摘要
Terahertz spectroscopy was used to study the sintering process of traditional ceramic by scanning sample with different final temperatures (from 100-1450 degrees C). Absorption coefficient (alpha) and refractive index (n) were obtained with different final temperatures. The sintering process was divided into four stages on the basis of a 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.
