Zero-shrinkage ceramic composite material and preparation method thereof
The invention provides a zero-shrinkage ceramic composite material and a preparation method thereof. Bismuth trioxide, boron nitride and aluminum oxide are used as raw materials, a pre-sintered material is obtained through ball-milling mixing and pre-sintering, a binder is added into the pre-sintered material, then granulation, compression molding and sintering are conducted, the zero-shrinkage ceramic composite material is prepared through a solid-phase sintering method, and the shrinkage rate, the mechanical property and the heat conductivity can be well considered; or a solvent, a dispersing agent, a binding agent and a plasticizer are added into the pre-sintered material through a tape casting method, uniform slurry is obtained through ball milling, the mixed slurry is subjected to tape casting to prepare green ceramic chips, the green ceramic chips are cut, then glue discharging and sintering are conducted, the zero-shrinkage ceramic composite material is prepared, the shrinkage rate of a single-layer sintered sheet is 5% or below, and the shrinkage rate of a five-layer laminated sintered sheet is 1% or below. The preparation process is simple and easy to implement, and has wide application prospects in the fields of electronic packaging, precision part manufacturing and dentistry.
本发明提供了一种零收缩陶瓷复合材料及其制备方法。以三氧化二铋，氮化硼和氧化铝三种物质为原料，经过球磨混合、预烧得到预烧物料，在预烧物料中加入粘结剂后造粒、压制成型、烧结，通过固相烧结法制得零收缩陶瓷复合材料，可以很好的兼顾收缩率、力学性能和热导率；或者通过流延法，在预烧物料中加入溶剂、分散剂、粘结剂和塑化剂，球磨得到均匀浆料，将混合浆料流延成型制成生瓷片，生瓷片经裁剪后排胶、烧结，制得零收缩陶瓷复合材料，单层烧结片的收缩率为5％以下，五层叠层烧结片的收缩率为1％以下。本发明制备工艺简单易行，在电子封装领域，精密零件制造领域，牙科领域均具有广阔的应用前景。
