Specifications of Industrial Ceramic High Pure 99% 99.7% Boron Nitride Metal Melting Crucibles

These crucibles handle extreme heat well. They withstand temperatures up to 2100°C in inert gas or vacuum. Crucibles melt metals like gold, silver, platinum, palladium, copper, aluminum, and their alloys. Crucibles work with semiconductors and special glasses too. Crucibles offer excellent thermal shock resistance. Crucibles resist cracking when heated or cooled very fast. Crucibles provide strong chemical inertness. They resist attack from most molten metals, slags, and acids. Crucibles show superb non-wetting behavior. Molten metal doesn’t stick to the crucible surface. This makes pouring easier and reduces waste. Crucibles feature high thermal conductivity. Heat spreads evenly through the crucible wall. This helps achieve consistent melt temperatures. Crucibles come in two main purity grades. The standard grade is 99% pure boron nitride (BN). The premium grade is 99.7% pure BN. Higher purity improves performance slightly. Higher purity crucibles last longer under harsh conditions. Crucibles are made from hot-pressed ceramic boron nitride. This process creates a dense, strong structure. Crucibles are available in various shapes and sizes. Common shapes include cylinders, cones, and rectangles. Sizes range from small laboratory scales to larger industrial capacities. Crucibles are electrically insulating. Crucibles are machined precisely for a smooth finish. Crucibles are fragile. Crucibles require careful handling to avoid chipping or breaking. Crucibles are essential tools for high-temperature metal processing. Crucibles ensure clean melts and long service life. Crucibles are chosen for demanding foundry, lab, and production settings. Crucibles offer reliable performance melting reactive or high-purity materials.

Applications of Industrial Ceramic High Pure 99% 99.7% Boron Nitride Metal Melting Crucibles

Industrial ceramic crucibles made from high-purity boron nitride offer great solutions for demanding metal melting jobs. These crucibles come in 99% and 99.7% pure grades. This high purity is essential. It prevents unwanted contamination of valuable metals during melting. Boron nitride itself is a special material. It handles extreme heat very well. It resists thermal shock. This means the crucible won’t easily crack when heated or cooled fast. You see this material in many tough industrial settings.

People use these crucibles for melting reactive metals. Metals like aluminum, magnesium, and copper alloys need clean handling. Boron nitride crucibles deliver that. They also work well for precious metals. Gold, silver, and platinum demand pure melting conditions. Contamination ruins their value. These crucibles protect that investment. Boron nitride crucibles are also vital in semiconductor crystal growth. Silicon and germanium crystals require absolute purity. The crucible material must not add impurities. High-purity boron nitride ensures this.

The surface of a boron nitride crucible is non-wetting. Molten metal does not stick to it. This makes pouring easier. Cleanup becomes simpler too. The crucible lasts longer because of this property. These crucibles withstand incredibly high temperatures. They are stable even above 2000°C. Few other materials can do this consistently. Their chemical inertness is another big plus. Boron nitride doesn’t react with most molten metals. It also resists attack from many fluxes. This keeps the melt pure and extends crucible life.

Durability is a key benefit. Boron nitride crucibles resist erosion. They survive repeated heating and cooling cycles. This toughness saves money over time. You replace crucibles less often. Handling these crucibles needs care. They are ceramic. They can break if dropped or hit hard. Always follow the maker’s guidelines for use and care. Using the right grade, 99% or 99.7%, matters. It depends on the specific metal and process requirements. Choosing the correct purity ensures top performance.

5 FAQs of Industrial Ceramic High Pure 99% 99.7% Boron Nitride Metal Melting Crucibles

Here are five key questions about our Industrial Ceramic High Purity Boron Nitride Crucibles (99% & 99.7%):

Why pick boron nitride for metal melting crucibles? Boron nitride crucibles don’t stick to molten metal. This non-wetting property means cleaner pours and less leftover material. They handle sudden temperature changes very well. Crucibles won’t crack easily when heating fast or cooling down fast. This is vital for repeated melting cycles.

What’s the highest temperature these crucibles can take? Crucibles work continuously up to 1800°C in inert gas or vacuum. They withstand short bursts to 2100°C. Avoid using them above 900°C in regular air. Oxygen makes them oxidize faster. Always stick to the recommended atmosphere for maximum life.

How does purity (99% vs 99.7%) matter? Higher purity means fewer impurities. 99.7% BN crucibles are cleaner. They are better for melting very reactive metals or alloys needing ultra-clean melts. They also degrade slower than 99% purity crucibles at high temperatures. This offers longer service life for demanding applications.

How long does one crucible last? Crucible lifespan depends heavily on the metal melted, the temperature used, and how often you use it. Melting aluminum or copper usually gives good life. Melting aggressive metals like titanium or zirconium wears them down faster. Expect shorter use. Proper handling and correct atmosphere extend usable time significantly.

How do I care for these crucibles? Handle them carefully. Boron nitride is strong but brittle. Avoid impacts. Clean out metal residues after each use. Let the crucible cool completely first. Use gentle tools like soft brushes or wood scrapers. Never use metal scrapers or abrasive cleaners. They scratch the smooth surface. Store crucibles in a dry place away from bumps.
