An electronics materials manufacturer was experiencing inconsistent purity results in a high-temperature melting process using standard alumina crucibles.
The Challenge
Trace reactions between the alumina crucible and the melt chemistry were introducing contamination levels that occasionally failed downstream quality specifications.
The Solution
Switching to yttria-stabilized zirconia crucibles, chosen specifically for chemical inertness against this melt chemistry, eliminated the reaction pathway causing contamination.
The Result
The manufacturer reported consistent purity compliance after the switch, despite the higher per-unit cost of zirconia versus alumina — justified by eliminating rework and failed batches.
