Procedure

In a similar test evaluation following the procedure described in the example above, calcium oxide based and calcium oxide-boric acid based pigments were prepared and evaluated for inhibitor efficiency. CaO.H3BO3.2Mn3O4 may also be written CaO.1/2B2O3.2Mn3O4 since boric acid is expected to lose a mole of water during the sintering operation. 68.6 Grams of manganomanganic oxide with a mean particle size of 2 microns were mixed with 8.4 grams of calcium oxide with a 2 micron particle size using a high intensity mixer. It was heated in a crucible at 600° C. for 1 hr. and then milled as in Example 1. Similarly a ratio of 1 mol of calcium oxide, 1 mol of boric acid, and 2 mols of manganomanganic oxide were prepared and sintered at 600° C. for 1 hr. 12.4 Grams of micronized boric acid (2 microns), 5.6 grams of calcium oxide and 45.7 grams of Mn3O4 were used during the sintering.
