FAQ

How does the crucible perform under rapid temperature changes?

The high-purity alumina and controlled density help mitigate thermal shock effects during rapid heating and cooling cycles. However, extreme gradients may induce microcracking. Adjust heating rates to maintain structural integrity.

How does the purity of alumina affect its chemical stability?

With a purity of ≥99%, impurity-driven defects are minimised. This enhances chemical inertness at elevated temperatures, reducing the risk of contamination or reaction with process materials.

What quality control measures ensure dimensional consistency in production?

SAM implements precision sintering with regular optical inspections and mechanical gauging. These measures verify that each crucible meets stringent dimensional and density tolerances throughout production.
