Characterization and performance analysis of a new stoneware

Guangdong Baojue New material Industry Co., Ltd fired stoneware with local rock and ore as main raw material. The material and properties of stoneware were characterized in this paper. The composition of stoneware was analyzed by inductively coupled plasma emission spectroscopy (ICP-AES) and X-ray fluorescence spectroscopy (XRF). The phase composition and microstructure of stoneware were analyzed by XRD and metallographic microscope. In this paper, the full-emittance, the air negative ion concentration, the content of the toxic component and the chlorine-removing ability were tested, and the soaking test of the Chinese liquor was carried out. The results showed that stoneware was an excellent material for drinking utensils and was beneficial to human health. (paper)
