Typical Applications

BN Crucibles are widely used in:

• Metal Evaporation & Deposition: Ideal for high-purity metal evaporation in semiconductor and photovoltaic industries, minimizing contamination risks.

• Molten Metal/Glass Handling: Resistant to corrosion from molten aluminum, copper, precious metals, and glass, ensuring continuous production.

• Powder Metallurgy & Casting: High-temperature molds and support components (e.g., C-BN-A1, C-BN-A2, C-BN-S1) enhance precision and efficiency in alloy forming.

• AlN/Si₃N₄ Substrate Sintering: Essential for high-purity sintering of AlN (aluminum nitride) and Si₃N₄ (silicon nitride) ceramic substrates, widely used in electronics and optoelectronics. Our crucibles prevent contamination and withstand extreme sintering temperatures, as validated by leading Japanese substrate manufacturers.
  

• High-Temperature Furnace Components: Insulating sleeves and heater protection (e.g., C-BN-Z) reliably operate in environments exceeding 1800°C.

FAQ: “What exactly is a BN crucible and why choose it?”
Answer:
BN crucible refers to a crucible made of Boron Nitride. Its main advantages are:
Ultra-high temperature resistance: In an inert atmosphere (such as argon and nitrogen), its long-term use temperature can reach more than 2000°C;
Chemical inertness: It can withstand a variety of highly corrosive metals and compounds, suitable for metallurgy and special ceramic melting;
Thermal shock stability: It exhibits excellent thermal shock resistance to rapid temperature changes.

FAQ: “What is the maximum temperature BN crucibles can withstand in different atmospheres?”
Answer:
In an inert atmosphere (such as argon and nitrogen): Users generally report that its maximum temperature is around 2100°C, sometimes even higher;
In air or oxygen-containing environment: The temperature is generally recommended to be controlled within 900°C to avoid surface oxidation or structural damage.

FAQ: “Are BN crucibles easy to machine and maintain?”
Answer:
Processability: BN materials are brittle, but their low friction coefficient and excellent wear resistance make them easy to machine and shape by laser cutting or precision grinding with high precision.
Maintenance: The most common cleaning method is non-mechanical cleaning with inert cleaning agents; however, it is recommended to check for microcracks or wear before and after use to prevent problems during high-temperature operation.

FAQ: “How do I choose the right BN crucible for my application and what should I watch out for?”
Answer:
Choice: It depends on the temperature requirements, chemical media aggressiveness and dimensional requirements of the specific application (such as melting metals, glass, ceramic processes, etc.).
Check the technical data provided by the manufacturer (including thermal conductivity, density, porosity, etc.);
If high temperature and high pressure conditions are used for a long time, strength and thermal shock resistance should be emphasized.
For laboratory use, specifications and accuracy requirements are usually relatively loose.
Precautions for use: Check regularly for cracks or wear; when the temperature rises sharply, it is recommended to preheat the machine to reduce thermal stress shock.

FAQ: "What about the cost and market availability of BN crucibles?"
Answer:
Price range: Due to the high manufacturing process and purity requirements, the price of BN crucibles is higher than that of traditional ceramic crucibles, but due to its high temperature resistance and corrosion resistance, it plays an irreplaceable role in specific fields (such as aerospace, nuclear energy);
Supply status: At present, the world's major suppliers of boron nitride are concentrated in China, the United States, Germany and Japan. Although China's boron nitride ceramics can reach 90% of the world's top level, the price is only about one-third of the top products.
