Whiteware Bodies without Kaolin
Original language description
Whiteware is a traditional ceramic material that has been manufactured for centuries from a mixture of kaolin + quartz + feldspar. Replacement of kaolin by calcium aluminate cement can increase the strength of green bodies, reduce the coefficient of linear thermal expansion and enhance the whiteness of fired products. A negative aspect of using calcium aluminate cement in ceramic bodies is reduced sintering activity and therefore, need for a higher firing temperature. Sodium hexametaphosphate admixture was also found to be very suitable for creation of calcium aluminate cement-based whiteware bodies with low porosity after firing. Use of this deflocculant increased the modulus of rupture (MOR) and bulk density of dried green bodies. Sodium hexametaphosphate also decreases the water content needed to achieve optimal viscosity for slip casting.
