The present disclosure provides a method for making a housing for a mobile communication device, comprising: step S1: mixing a zirconia ceramic powder, a solvent and a binder to form a mixed slurry; step S2: tape-casting the mixed slurry to form a single layer of base membrane band, and then preparing at least one layer of laminated membrane band on the base membrane band by lamination and isostatic pressing, so as to form a laminated body; step S3: debinding, sintering and hot-bending the laminated body to obtain a compact ceramic housing for a mobile communication device; wherein step S3 is performed in one common step combining sintering and hot bending or by hot bending a flat sample, which has beneficial effects such as high yield, low production cost, good product compactness, good fracture toughness, and good flexural strength, etc. |
