Frequently Asked Questions

Q1: How does the sintering process influence the material properties?
A1: The controlled sintering process refines the microstructure, reducing porosity and enhancing thermal stability. This results in improved resistance to thermal shock and chemical attack, which is crucial for maintaining performance in high-temperature environments.

Q2: What quality control methods are employed during production?
A2: Stanford Advanced Materials (SAM) incorporates in-line X-ray diffraction and surface profilometry to monitor phase composition and microstructure uniformity. These methods help verify that each batch maintains the specified material properties and meets rigorous industrial standards.

Q3: Can the crucible be customised for specific industrial applications?
A3: Yes, customisation options are available. Adjustments in dimensions, wall thickness, and thermal treatment parameters can be made to suit different operational environments. Customers are encouraged to discuss their technical requirements for tailored solutions.
