5 FAQs of Anti-Corrosion Boron Nitride Bn Ceramic Rectangular Crucible

**What is boron nitride (BN) ceramic, and why is it used for crucibles?**
Boron nitride ceramic is a synthetic advanced material known for exceptional thermal stability, chemical inertness, and low thermal expansion. It’s composed of boron and nitrogen atoms in a hexagonal lattice structure, similar to graphite but with superior performance in high-temperature and corrosive environments. BN ceramic is ideal for crucibles because it resists oxidation up to 900°C in air, withstands extreme temperatures (up to 3000°C in inert gases), and doesn’t react with most molten metals, acids, or alkalis, ensuring purity in high-precision applications.

**How does the anti-corrosion property of BN ceramic benefit users?**
The anti-corrosion nature of BN ceramic crucibles ensures longevity and reliability when handling aggressive materials like molten aluminum, lithium, or glass. Unlike traditional crucibles made of graphite or metals, BN doesn’t degrade when exposed to reactive substances, reducing contamination risks and maintenance costs. This makes it suitable for industries such as metallurgy, semiconductor manufacturing, and aerospace, where material purity and equipment durability are critical.

**What temperature range can the BN rectangular crucible withstand?**
BN ceramic crucibles operate effectively in temperatures up to 3000°C in inert or vacuum environments and up to 900°C in oxidizing atmospheres. Their low thermal expansion coefficient minimizes cracking under rapid temperature changes, making them ideal for processes like vacuum coating, single crystal growth, or high-temperature sintering.

**What applications are BN rectangular crucibles best suited for?**
These crucibles are widely used in high-precision industries, including metal refining (e.g., aluminum, gold), semiconductor production (melting silicon or gallium arsenide), and glass processing. They’re also ideal for laboratory research, aerospace component testing, and any environment requiring contamination-free handling of corrosive or high-purity materials.

**How should BN ceramic crucibles be handled and maintained?**
While BN ceramic is mechanically robust, avoid mechanical impact or sudden thermal shocks to prevent cracks. Clean residues with non-abrasive methods, such as diluted hydrochloric acid or ultrasonic cleaning. Store in a dry environment to prevent moisture absorption, though BN’s hydrophobicity minimizes this risk. Regular inspection for surface wear ensures optimal performance over time.
