由于中国产生了大量的瓷砖抛光废料，因此这种废渣的回收利用变得非常重要。以瓷砖抛光废料为主要原料，成功制备了泡沫陶瓷。在本研究中，加入了SiC作为泡沫剂，并对泡沫机理进行了探讨。结果表明，SiC的最佳掺量为1%。此外，为了获得结构更好的泡沫陶瓷，在原料中加入磷酸钠作为泡沫稳定剂。研究了该添加剂对泡沫陶瓷微观结构和性能的影响。结果表明，磷酸钠的最佳添加量为2-3%。
Due to the large amount of ceramic tile polishing waste generated in China, the recycling of this waste residue becomes important. Herein a foam ceramic was successfully produced by using ceramic tile polishing waste as main raw material. In this research, SiC was added as the foam agent, and the foaming mechanism was also investigated. The results showed that the best dosage of SiC was 1%. Furthermore, in order to obtain a foam ceramic with better structure, the sodium phosphate was added in raw materials as foam stabilizer. The influence of this addition on the microstructure and properties of foam ceramic was investigated. It was found that the optimum additive amount of sodium phosphate is 2–3%.
