6. Silicate ceramics Introduction The main types of silicate ceramics are based either on alumosilicates (→ kaolin or clay based ceramic such as porcelain, earthenware, stoneware and bricks; system K2OAl2O3 SiO2) or on magnesium silicates (→ talcbased technical ceramics such as steatite, cordierite and forsterite ceramics; system MgOAl2O3SiO2).
The obtained CA/CaCO 3 sheet was then immersed into a coagulation bath of 300 mL water for 2 days in order to induce NIPS process. A schematic diagram of the preparation of CA/CaCO 3 sheet by NIPS is presented in Fig. 4.
Liquid transportation hydrocarbon fuels and various other chemical products can be produced from syngas via the wellknown and established catalytic chemical process called FischerTropsch (FT) synthesis, named after the original German inventors, Franz Fischer and Hans Tropsch in the 1920s. During World War II, FT synthesis provided the needed liquid hydrocarbon fuels for the German war .

Carbonation is a slow process and takes place continuously until the slaked lime has absorbed as much CO 2 as possible to form the lime putty. Ca(OH) 2 CO 2 = CaCO 2 O • Drying – At this stage the lime putty is a slurry containing 20 per cent precipitated calcium carbonate (PCC) and 80 per cent water. The water is removed as the slurry ...
