Tape casting Low viscosity The rheology of the suspension plays a critical role in the tape casting process. The key rheological properties include viscosity (η), shear-thinning behavior (pseudoplasticity), yield stress, thixotropy, viscoelasticity, and time-dependent stability. Low viscosity makes controlling the suspension during tape casting more difficult. Achieving higher thickness becomes more challenging, and the thickness may gradually decrease from the center toward the edges. It can also increase shrinkage during drying, and if the tape thickness is high, it may lead to warping during the drying process. In more severe cases, it can lead to non-uniform particle distribution in composite… [Read more]
