Abstract
The effect of various modifying additions to technical lignosulfonates used in the production of periclase (from fused and sintered periclase), chromite-periclase, and thermostable chromite-periclase articles is investigated. An acceptable strength for the green material for periclase articles is provided by lignosulfonates produced by the Kamsk Wood-Pulp and Paper Plant. The recommended modifying addition is carbamide. An addition of tall oil reduces the strength of greenware but improves the properties of articles after firing. Lignosulfonates with additions of carbamide, aluminum chloride, and titanium sulfate are considered the most efficient for chromium-containing articles.
