Powder for injection, binder, preparation processes and ceramic filter
The invention relates to the technical field of ceramic filters, and particularly discloses powder for injection, a binder, preparation processes and a ceramic filter. The powder for injection is composed of five elements, namely Ca, Ti, Sm, Al and O. The molar percentages of Ca, Ti, Sm and Al are 25 mol%-35 mol%, 0 mol%-10%, 25 mol%-35 mol% and 25 mol%-35 mol%, respectively; and the particle sizeD50 of the injection powder is 1 [mu]m to 5 [mu]m. A prepared feed is good in fluidity and convenient to inject, and a filter product with a complex shape can be prepared from the feed; an injected green body is complete in structure, the green body is small in shrinkage and good in appearance after injection, and macroscopic air holes and holes do not exist in the cross section of the green body; degreasing byproducts of a feed product are carbon dioxide and water, so no pollution is caused to the environment; and a corresponding sintered blank product of the filter is 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、粘结剂、制备工艺及陶瓷滤波器,所述注射用粉由Ca、Ti、Sm、Al、O五种元素组成,并且Ca、Ti、Sm、Al四种元素的摩尔百分比为:25mol%~35mol%的Ca、0mol%~10%mol的Ti、25mol%~35mol%的Sm和25mol%~35mol%Al;所述注射用粉料的D50粒径为1μm~5μm。本发明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,喂料产品脱脂副产物为二氧化碳和水,对环境无污染,对应滤波器烧坯产品密度均匀、变形小,尺寸精度高。
