Method for preparing ceramic microbeads, ceramic microbeads and application thereof
The invention relates to the field of ceramics, and discloses a method for preparing ceramic microbeads. The method comprises the following steps: slurry containing an organic monomer, a cross-linkingagent, water-soluble alginate, ceramic powder, a sintering aid, an initiator and a dispersing agent is prepared, and the organic monomer, the cross-linking agent, the water-soluble alginate, the initiator and the dispersing agent are dissolved in the slurry, wherein the number-average molecular weight of the water-soluble alginate is not lower than 4000; the slurry prepared in the step (1) is fedinto an oil phase containing a catalyst in the form of liquid drops, and primary gel casting is carried out to obtain cured microspheres; the cured microbeads obtained in the step (2) are fed into anaqueous solution of a calcium source, and secondary gel casting is carried out to obtain hardened microbeads; and the hardened microbeads obtained in the step (3) are sintered. The ceramic microbeadprepared by the method has the advantages of high density, high strength, high wear resistance, low surface roughness, low out-of-roundness and low oil phase loss.
本发明涉及陶瓷领域，公开了一种制作陶瓷微珠的方法，该方法包括以下步骤：配制含有有机单体、交联剂、水溶性海藻酸盐、陶瓷粉体、烧结助剂、引发剂和分散剂的浆料，所述有机单体、交联剂、水溶性海藻酸盐、引发剂和分散剂溶解在所述浆料中，其中，所述水溶性海藻酸盐的数均分子量不低于4000；将步骤(1)配制的浆料以液滴的形式送入含有催化剂的油相，进行一次注凝成型，得到固化微珠；将步骤(2)所得固化微珠送入钙源的水溶液，进行二次注凝成型，得到硬化微珠；将步骤(3)所得硬化微珠进行烧结；采用本发明的方法制备的陶瓷微珠具有致密度高、强度高、耐磨度高，且表面粗糙度低、不圆度低和油相损耗低的优点。
