Procedure
Cobalt Micelle: Weighed 10 grams of cobaltic oxide (Co2O3), and added to 500 ml of distilled water. Added 11.5 ml of glacial acetic acid to yield a cobalt (III) acetate in solution. Added 100 grams of chrysotile (Union Carbide, high purity, grade 7) and diluted to 3.5 liters with distilled water. Heated the suspension to 100° C. and added 180 ml of 1 N sodium hydroxide to precipitate a cobalt micelle oxide onto the asbestos surface. Continued to heat and stir for 30 minutes. Removed from heat and allowed to cool. Collected the product by vacuum filtration on a Whatman #1 filter. A blue product was obtained. The product was air dried for 16 hours. The filter cake was dried at 330° F. for 90 minutes. The dry cake was fiberized by use of a blender at high speed for 1 minute. The sample was completely dissolved for elemental analysis by treatment with 20% by weight sodium peroxide at 850° C. Elemental analysis of the product is shown in Table I. Table II shows that the treatment increased the HF insoluble matter to 32% compared to 8.6% for an untreated chrysotile sample.
