Claims
- 1. A method of processing ceramics which comprises forming a slurry consisting of ceramic material and a dispersant; said ceramic material forming between 65 percent and 80 percent, by weight, of said material and being a mixture of metal oxides, and spray drying said slurry;
- characterized in that said dispersant consists essentially of at least one member selected from the group consisting of polyethylenimine and mixtures of polyethylenimine and ammonium citrate.
- 2. A method as recited in claim 1 in which said slurry has a solids content of approximately 75 percent.
- 3. A method as recited in claim 2 in which said ceramic material is a mixture of oxides suitable for forming a ferrite.
- 4. A method as recited in claim 3 in which said ferrite is a MnZn ferrite.
- 5. A method as recited in claim 3 in which said dispersant is polyethylenimine, said dispersant having a concentration greater than 0.25 weight percent.
- 6. A method as recited in claim 5 in which said concentration is between 0.75 and 1.00 weight percent.
