Concentrated fungicidal compositions, in the form of water-dispersible granules are disclosed which contain:

Water-dispersible granules of phosphite fungicidal products

Shaped articles having improved mechanical properties, e.g., stronger catalysts and catalyst supports, are produced by shaping a mass of particulate material, e.g., ceramic powder, into the form of the desired final article, the particulate material including a microbially produced poly-saccharide compound, and then consolidating the shaped article by heat treating same, e.g., to sintering or calcination temperatures.

Mechanically improved shaped articles

Novel aqueous lubricant dispersions contain at least one rare earth halide, e.g., cerium trifluoride, and at least one polymeric dispersing agent therefor, such at least one dispersing agent including:

Aqueous lubricant dispersions of rare earth halides

Novel lubricant compositions contain at least one rare earth halide, e.g., cerium trifluoride, and at least one surfactant including a hydrophobic moiety and a hydrophilic moiety, such hydrophilic moiety comprising ethylene oxide and/or propylene oxide units and, optionally, hydrophilic functional groups, dispersed in an oily medium compatible therewith.

Lubricant dispersions of rare earth halides in an oily medium

Surfactant compositions in an acidic or neutralized form containing a mixture of at least one polyoxyalkylenated phosphoric acid monoester and at least one polyoxyalkylenated diester and a nonionic polyoxyalkylenated compound wherein the phosphoric acid diester:phosphoric acid monoester molar ratio before neutralization, if carried out, is at least equal to 0.9:1 and the phosphoric acid monoester and phosphoric acid diester content is at least 1 mol %, preferably at least 50 mol % of said composition. The surfactant compositions are prepared by phosphatization of a nonionic polyoxyalkylenated compound at a temperature of from about 35.degree. to about 45.degree. C. followed by maturing at from about 40.degree. to about 60.degree. C., in a stirred turbulent state. The compositions are useful in the formulation of active substances in the form of microgranules and flowables.
