Ceramics/industrial ceramics

Lignosulfonates have a broad range of uses in the manufacture of industrial ceramics.

This includes the manufacture of oxide ceramics for refractory purposes (e.g. MgO ceramics; magnesite stones) or in the technical area of functional ceramics (e.g. Al2O3 ceramics), as well as in the area of non-oxide ceramics such as silicon carbide ceramics.

Magnesium lignosulfonate is added to the raw ceramic mass or to the slurry as a bonding agent to increase the green strength of the pressed blanks. The effectiveness of this can be influenced by the manufacturing process of the lignosulfonate and by the raw wood material used.
