6. Calculate the viscosity of a water-base suspension containing 45 wt% of alumina (d = 3.99 g/cm)? Represent the behaviour in case of reopecticity and thixotropicity. 7. The ceramic component (with axial symmetry) shown in the figure has to be produced. Which forming process can be used. Why? Are there any critical aspects that need to be changed or shapes to be modified? = 8. A green disc (thickness 4.00 mm diameter 60.0 mm) shall be produced = by uniaxial pressing. Silicon carbide granules (fill density =32%, mean particle size = 0.4 m, granule density 46%, granule mean size 180 m) are used. The compaction ratio (Dpressed/D) is 1.8. The spring-back is 1.8%. The maximum applied pressure is 70 MPa. Specify the fundamental dimensions of the die and the minimum displacements. 9. The following shapes (with axial symmetry) shall be produced by the indicated technology. Specify the system to be used (... powder, slurry, paste....) and any critical issue or modification to the shape. uniaxial pressing extrusion slip casting 10. Estimate the effect of gravity on the thickness of the cake in slip casting for mould height variable from 20 cm to 1 m. 11. Compare the drying shrinkage for particles of 1.0 and 0.01 m in simple cubic packing when the
