SYNTHETIC CLAY FOR CERAMICS AND PROCESS FOR PREPARING THE SAME |
摘要 |
Clay constitutes the three major elements of pottery and porcelain together with silica stone and feldspar. In recent years, however, a good clay having a high plasticity and a low impurity level is being exhausted. The invention provides a synthetic clay rich in water retention and the amount of watery coating formed and possessing plasticity and properties equal or superior to natural clay and a process for preparing the same. The synthetic clay comprises 30 to 65 % by weight of amorphous silica, 30 to 65 % by weight of alumina trihydrate, and 2 to 20 % by weight of at least one of sepiolite, palygorskite, and bentonite. It may be in the form of a slurry, a hydrous clay prepared by dehydrating a slurried synthetic clay, or a mass or dry powder prepared by dehydrating a slurried synthetic clay and drying the dehydrated clay.
