      Zinc–magnesium titanate dielectrics/nickel–zinc–copper ferrite layer composites were prepared by tape-casting technique combined with a uniaxial pressure shaping technique. The sintering and camber development of the composites were investigated. The results show that the difference of shrinkage in the later stages of sintering is the main cause of camber distortion. To eliminate or decrease the camber, a new method semi-fixed uniaxial pressure technique (SUP) was proposed. This method uses uniaxial pressures by which different radial densities can be introduced when one layer's edge is clamped and the other is free while laminating two different layers. The results obviously show that the SUP technique can decrease the camber and the camber curvature shows an inverse quadratic dependence on the applied pressure.
