Making outline

Calcine, wet mill, orient/press, sinter and finish strontium ferrite
Research detailed preparation, operation and acceptance. Numerical limits and suitability are not specified.

What remains unresolved

Candidate method, complete inventory, caller demands and physical compatibility require research and review.
Complete inventory, source-supported recipe, independent acceptance, caller demands, stock/loss and availability remain unreviewed.
