5 FAQs of Standard 99.5 Alumina Refractory Melting Ceramic Crucible

What’s the highest temperature this crucible handles?
This crucible withstands temperatures up to 1800°C (3272°F). Its high alumina content provides excellent heat resistance. It’s suitable for melting most metals and alloys. Exceeding this limit risks damage.

Will it crack from sudden temperature changes?
This crucible offers good thermal shock resistance. It manages moderate heating and cooling rates well. Avoid extreme temperature swings. Placing a cold crucible directly into a hot furnace is bad. Preheating gradually is best practice. This prevents cracking.

What metals can I melt in it?
Use it for gold, silver, copper, platinum, and related alloys. It works well with many non-ferrous metals. Avoid highly corrosive materials. These include strong alkalis or specific reactive metals like titanium. These materials attack the alumina.

How long will one crucible last?
Lifespan varies significantly. It depends on the metal melted, peak temperatures, cycle frequency, and handling. Using it within its limits helps. Proper preheating and avoiding thermal shock extends life. Expect multiple uses under careful conditions. It won’t last forever.

How do I clean it after melting?
Let the crucible cool completely first. Remove any leftover metal slag carefully. Use a tool that won’t scratch the surface. Avoid harsh chemicals or aggressive scraping. Gentle mechanical removal is safest. Inspect for cracks before reuse.
