Ceramifiable ethylene-vinyl acetate (EVA) copolymer composites were prepared through incorporating silicate glass frits (SGF) and ammonium polyphosphate (APP) into the EVA. The ceramic residues were obtained by firing all samples at different temperatures. The effect of APP on the self-supporting property and shape stability of the composites were studied, and the effect of APP on the flexural strength and water absorption of the ceramic residues were investigated. The results show that the addition of APP improved the self-supporting property and the flexural strength of the composites due to the increased crystal phase. The shape stability and the porous structure of the residues increased due to water and NH₃ released from the thermal decomposition of APP. XRD and SEM analysis demonstrated that APP promotes the precipitation of sodium phosphate and cristobalite. Furthermore, the growth process of the crystal was investigated by crystallization kinetic.

通过将硅酸盐玻璃粉（SGF）和多磷酸铵（APP）掺入EVA来制备可陶瓷乙烯-乙酸乙烯酯（EVA）共聚物复合材料。通过在不同温度下烧制所有样品获得陶瓷残留物。研究了APP对复合材料自支撑性能和形状稳定性的影响，并研究了APP对陶瓷残余物的抗弯强度和吸水率的影响。结果表明，由于晶相增加，APP的加入改善了复合材料的自支撑性能和抗弯强度。残留物的形状稳定性和多孔结构由于水和NH ₃而增加从APP的热分解中释放出来。XRD和SEM分析表明APP促进了磷酸钠和方石英的沉淀。此外，通过结晶动力学研究了晶体的生长过程。
