Foamed ceramic and preparation method thereof
The invention discloses foamed ceramic and a preparation method thereof, and belongs to the technical field of ceramic materials.The preparation method of the foamed ceramic comprises the steps that an organic foam carrier is pretreated, specifically, polyurethane foam is soaked in an alkali liquor and then soaked in a pretreatment solution containing sodium aluminum sulphide silicate, and the organic foam carrier is obtained; a ceramic slurry is prepared: ceramic powder, a solvent and an additive are mixed to obtain the ceramic slurry; a ceramic precast block is prepared: internal air is removed from the pretreated organic foam carrier, the pretreated organic foam carrier is conveyed into the ceramic slurry, a slurry soaking process is carried out, and drying is carried out to obtain a foamed ceramic precast block; sintering preparation of the ceramic: pressureless sintering on the foamed ceramic precast block is carried out to obtain the foamed ceramic. According to the method, the organic foam carrier is pretreated, the slurry hanging amount of the organic foam carrier is increased, and the foamed ceramic with high porosity, high volume shrinkage rate and good compressive strength is obtained.
本发明公开了一种泡沫陶瓷及其制备方法，属于陶瓷材料技术领域，本发明的泡沫陶瓷的制备方法包括：有机泡沫载体的预处理：聚氨酯泡沫经碱液浸泡后，经含有硫化硅酸铝钠的预处理溶液浸渍后得到有机泡沫载体；陶瓷浆料的配制：将陶瓷粉体、溶剂和添加剂混合得到陶瓷浆料；陶瓷预制块的制备：将预处理有机泡沫载体除去内部空气后置于陶瓷浆料中进行浸浆工序后干燥得到泡沫陶瓷预制块；陶瓷的烧结制备：泡沫陶瓷预制块无压烧结得到泡沫陶瓷。本发明方法中对于有机泡沫载体的预处理，提高有机泡沫载体的挂浆量，并得到气孔率高、体积收缩率高、抗压强度好的泡沫陶瓷。
