Method for preparing ceramic by pouring poly-gamma-glutamic acid gel
The invention relates to a method for preparing ceramic by pouring poly-gamma-glutamic acid gel, and belongs to the technical field of ceramic preparation. The method comprises the following steps: dissolving poly-gamma-glutamic acid in water, then adding ceramic powder, fully mixing, adjusting the pH value of the mixed slurry to 2-7, adding a cross-linking agent, fully stirring, injecting the obtained slurry into a grinding tool, carrying out in-situ polymerization to obtain a ceramic green body with a macromolecular network structure, and sintering to obtain ceramic; the ceramic powder is one or more of mullite, silicon nitride, silicon carbide, zirconium boride, aluminum oxide and anorthite. As a green and environment-friendly gel casting system with high solid loading capacity and low viscosity, the gel casting system is used for preparing ceramic elements with high quality and complex shapes. The poly-gamma-glutamic acid gel system provided by the invention has a unique three-dimensional network structure, can realize preparation of high-performance and high-precision ceramic, and is convenient to popularize and apply.
本发明涉及一种聚‑γ‑谷氨酸凝胶浇注制备陶瓷的方法，属于陶瓷制备技术领域。该方法为将聚‑γ‑谷氨酸溶解于水中，然后加入陶瓷粉体，充分混合，调节混合料浆的pH为2‑7，加入交联剂，充分搅拌，将得到的料浆注入磨具内原位聚合得到大分子网络结构的陶瓷生坯，烧结得到陶瓷；所述陶瓷粉体为莫来石、氮化硅、碳化硅、硼化锆、氧化铝、钙长石中的一种或多种。本发明作为一种绿色环保，高固体负载量、低粘度的凝胶浇注体系，用于制备高质量、形状复杂的陶瓷元件。本发明聚‑γ‑谷氨酸凝胶体系具有独特的三维网状结构，能够实现高性能、高精度陶瓷的制备，便于推广应用。
