High-density and high-strength calcite ceramic and preparation method thereof
A calcite phase is a thermodynamic stable phase of calcium carbonate (CaCO3) and is abundant in reserves in nature. The invention discloses a high-density and high-strength calcite ceramic and a preparation method thereof.The ceramic is a block material of calcite-phase calcium carbonate and is prepared by mixing calcite powder with water, an acid solution or solid acid and then applying a certain intensity of pressure at the temperature ranging from room temperature to 200 DEG C. The density of the ceramic is 80% or above, and the strength of the ceramic is higher than that of the calcite-phase calcium carbonate. The strength is obviously higher than that of cement, natural rock and other traditional structural materials, and the method can be used in building, decoration and other traditional fields. Compared with natural calcite rock, the calcite ceramic disclosed by the invention has the advantages of high purity, controllable microstructure and the like, and can also be used in the high and new technical fields of medical bone regeneration, electronic industry and the like. Meanwhile, the calcite ceramic disclosed by the invention is simple in preparation process, low in preparation temperature, rich in raw material source and low in price, so that low-cost large-scale production is facilitated.
方解石相是碳酸钙(CaCO3)的热力学稳定相，在自然界中储量丰富。本发明公开了一种高致密度、高强度方解石陶瓷及其制备方法，该陶瓷是方解石相碳酸钙的块体材料，由方解石粉末与水、酸溶液或固体酸混合后，在室温至200℃的温度下、施加一定压强后制得，其致密度在80％以上，并具有明显高于水泥、天然岩石等传统结构材料的强度，可用于建筑、装饰等传统领域。与天然方解石岩石相比，本发明公开的方解石陶瓷具有纯度高、微结构可控等优点，因此还可用于医学骨再生及电子工业等高新技术领域。同时，本发明公开的方解石陶瓷制备工艺简单、制备温度低、原料来源丰富且价格低廉，因此有利于低成本的规模生产。
