Article Preview

The main chemistry ingredients of the shale in Baoding, China, are SiO2 and Al2O3, and the mineral components are quartz, feldspar and mica. The shale was sintered to produce pottery at 1000 ~ 1300°C and its deposit density and expansion ratio were measured. The compressive strength, apparent density, water absorption, etc, of some sintered samples with expansion ratio more than 1.5 were measured according to GB/T17431.2-1998. When sintered at 1150°C for 15 min, the expansion ratio of the shale is 1.96. When sintered at 1200°C for 10 min, the expansion ratio is 2.00. The performances of the prepared pottery accord with GB/T17431.2-1998: the compressive strength is 3.8MPa with the expansion ratio 1.96, the compressive strength is 4.2MPa with the expansion ratio 2.00. The water absorption is 4.9~5.8%, according with GB/T17431.2-1998.
