Technical Ceramics

Continuous monitoring and analysis of metallurgical processes requires precise and fail-proof instrumentation and evaluation methods. To ensure a product of constant quality and minimize rejects, it is essential to determine the melt purity by analyzing samples. Analysis crucibles of 3M™ Boron Nitride (previously ESK MYCROSINT®) are the preferred materials for analysis of almost all molten metals. The fact that they are not wetted and their low chemical reactivity almost entirely eliminates contamination of the material under analysis. Because 3M™ Boron Nitride materials feature excellent thermal shock resistance, the sample material can usually be taken directly from the melt.
