蜂窝陶瓷基材、蜂窝挤出模头以及蜂窝陶瓷基材的制造方法
摘要：
提供了蜂窝陶瓷基材(102)、其制造方法，以及配置成从陶瓷或形成陶瓷的材料批料挤出蜂窝陶瓷基材(102)的蜂窝挤出模头(408)。基材(102)可以包括限定了流动通道(108)的蜂窝网络的交叉壁(110)的格子，所述流动通道在蜂窝基材(102)的入口端(104)和出口端(106)之间延伸。每条流动通道(108)可以被多个交叉壁的通道壁(110)所限定，所述多个通道壁(110)中的至少两个包括凹的内表面(116)，其朝向对应流动通道(108)的中心(125)，从凹的内表面(116)的中心部分至朝向对应流动通道(108)的中心(125)的凹的角部分。
摘要（英）：

A honeycomb ceramic substrate (102), a method of making thereof, and a honeycomb extrusion die (408) configured to extrude a honeycomb ceramic substrate (102) from a batch of ceramic or ceramic-forming material is provided. The substrate (102) may include a lattice of intersecting walls (110) defining a honeycomb network of flow channels (108) extending between an inlet end (104) and an outlet end (106) of the honeycomb substrate (102). Each flow channel (108) may be defined by a plurality of channel walls (110) of the intersecting walls with at least two of the plurality of channel walls (110) including concave inner surfaces (116) facing a center (125) of the corresponding flow channel (108) from central portions of the concave inner surfaces (116) to concave corner portions facing the center (125) of the corresponding flow channel (108).
