Powder for injection, plastic-based binder, process and ceramic filter
The invention relates to the technical field of ceramic filters, specifically to a ceramic filter, a plastic-based binder, a process and a ceramic filter. The powder for injection is composed of fourelements, namely Mg, Ca, Ti and O, wherein the molar percentage ranges of the three elements including Mg, Ca and Ti are 45-55 mol%, 45-55 mol% and 0-10 mol%, respectively; and the particle size D50 of the powder for injection is 0.2-1 micron. According to the powder for injection, the plastic-based binder, the process and the ceramic filter provided by the invention, a prepared feed has good fluidity and is convenient to inject; and a filter product with a complex shape can be manufactured. An injection green body is complete in structure, small in shrinkage after injection, good in appearance and free of macroscopic air vents and holes in a cross section. Corresponding sintered filter blank products are uniform in density, small in deformation and high in size precision.
本发明涉及陶瓷滤波器技术领域，具体公开一种注射用粉料、塑基粘结剂、工艺及陶瓷滤波器，所述注射用粉料由Mg、Ca、Ti、O四种元素组成，其中，Mg、Ca、Ti这三种元素摩尔百分比范围分别为45mol％～55mol％的Mg、45mol％～55％mol的Ca和0mol％～10mol％的Ti；所述注射用粉料的尺寸为D50粒径0.2μm～1μm。本发明提供一种注射用粉料、塑基粘结剂、工艺及陶瓷滤波器，所制得喂料流动性好，方便注射；可制得形状复杂的滤波器产品。注射坯体结构完整且注射后生坯收缩小、外观良好、断面无肉眼可见气孔和孔洞。对应滤波器烧坯产品密度均匀、变形小，尺寸精度高。
