  • Method for producing ceramics from particle sheet material using cationic pulp
    Patent number: 3962389
    Abstract: Method for producing ceramics such as pottery, tiles, bricks and refractory materials which comprises the steps of: mixing in water inorganic fine particles having a negative .zeta.-potential in water and cationic cellulose pulp having a .zeta.-potential of +20 mV or higher; then forming a particle sheet material from said mixture in water using a sheet forming machine; firing said particle sheet material in an oxidizing atmosphere to burn off the cellulose pulp component in said sheet material; and firing further said particle sheet material to sinter the remaining inorganic fine particles. The use of said cationic cellulose pulp eliminated the need of synthetic polymer binders for inorganic fine particles.
