5 FAQs of Refractory Alumina Al2O3 Melting Ceramic Crucible Boat

What is a refractory alumina crucible boat? It is a container made from high-purity alumina ceramic. This material withstands extreme heat. The boat shape helps with pouring melted materials. You use it for melting metals in labs or industry. What temperatures can it handle? It works up to 1800 degrees Celsius. This suits most melting jobs. It stays strong without cracking or warping. Thermal shock resistance is good too. What materials can I melt? Precious metals like gold and silver work well. Copper and other non-ferrous metals are fine too. Avoid iron-based metals or alkaline materials. They damage the crucible faster. How long does it last? Lifespan varies with use. Proper handling gives 20 to 50 cycles. High temperatures or corrosive metals shorten this. Check for cracks or thinning before each use. Replace it if you see damage. How do I clean and maintain it? Let it cool completely after melting. Remove residue with a soft brush or wooden tool. Never use cold water on a hot crucible. Sudden temperature changes cause cracks. Store it dry and avoid impacts. Keep it separate from other labware.
