  • Varnish-bonded carbon-coated magnesium and aluminum granules
    Patent number: 4541867
    Abstract: Varnish-bonded, carbon-coated metal granules are provided, the metal granules being preferably selected from the group consisting of magnesium, aluminum and alloys thereof. The coating may optionally contain at least one calcium compound, e.g., at least one calcium compound selected from the group consisting of CaO, CaCO.sub.3, CaC.sub.2, CaSiO.sub.3, CaSi.sub.2, CaAl.sub.2 O.sub.4, portland cement and CaF.sub.2.
    Type: Grant

  • Process for producing varnish-bonded carbon-coated metal granules
    Patent number: 4533572
    Abstract: A process is provided wherein metal granules coated with a polymerizable oil are heated, while being mechanically mixed, to a polymerizing temperature to convert the oil coating to a varnish and the varnish coating thereafter heated to a higher temperature to decompose at least partially the varnish to carbon, thereby producing a carbon coating strongly bonded to the metal granules. The temperatures employed are below the melting point of the metal granules. The coating is preferably applied to magnesium, aluminum or alloys thereof for use as addition agents in steel, e.g., desulfurizing or deoxidizing agents, and may contain fine particles of at least one calcium compound.
