Key Features of PBN Crucibles and Liners<\/strong>
1. Superior thermal conductivity and thermal shock resistance<\/p>\n\n\n\n

2. Easy to clean and suitable for repeated use<\/p>\n\n\n\n

3. High chemical inertness; does not react with acids or bases at high temperatures<\/p>\n\n\n\n

4. Non-wetting to molten metals<\/p>\n\n\n\n

5. Controllable thermal conductivity<\/p>\n\n\n\n

6. Convenient to clean and reusable<\/p>\n\n\n\n

<\/div>\n\n\n\n


To ensure safe operation and prolong equipment life, we recommend limiting the use of PBN to temperatures not exceeding 1300\u00b0C, with a controlled cooling rate of less than 25\u00b0C per minute below 660\u00b0C. The crucible should be inspected between each use, and replaced immediately if any signs of cracking are detected.<\/strong><\/p>","protected":false},"excerpt":{"rendered":"
