可通过挤出包含草酸钠的混合物而获得的beta-氧化铝陶瓷
摘要：
本发明涉及包含如下组分的组合物用于通过挤出制备陶瓷模制品的用途：A)55‑90重量％氧化铝，B)5‑35重量％钠化合物，其在pH7和20℃下在水中具有≤300g/l的溶解度且可通过热方式几乎仅转化成作为唯一固体的氧化钠，C)0‑15重量％选自如下组的镁化合物和/或锂化合物：氧化镁、碳酸镁、硝酸镁、氧化锂、碳酸锂、硝酸锂，和D)0‑30重量％二氧化锆。
摘要（英）：

Use of a composition comprising A) from 55 to 90% by weight of aluminum oxide, B) from 5 to 35% by weight of a sodium compound which at a pH of 7 at 20° C. has a solubility in water of ≦300 g/l and can be converted by thermal means virtually exclusively into sodium oxide as only solid, C) from 0 to 15% by weight of a magnesium compound and/or a lithium compound selected from the group consisting of: magnesium oxide, magnesium carbonate, magnesium nitrate, lithium oxide, lithium carbonate, lithium nitrate and D) from 0 to 30% by weight of zirconium dioxide for producing a shaped ceramic body by extrusion.
