Overview of High Temperature Resistant 99.7% Boron Nitride Bn Ceramic Crucible

High Temperature Resistant 99.7% Boron Nitride Bn Ceramic Crucible ceramics are a class of advanced technical ceramics, often referred to as “white graphite.” They are renowned for their unique combination of properties, including high thermal conductivity, excellent electrical insulation, and outstanding thermal shock resistance. Available in various forms such as hot-pressed solids, coatings, and composites, BN ceramics are critical in demanding applications across aerospace, electronics, and metallurgical industries.

Features of High Temperature Resistant 99.7% Boron Nitride Bn Ceramic Crucible

Specifications of High Temperature Resistant 99.7% Boron Nitride Bn Ceramic Crucible

This boron nitride ceramic crucible handles extreme heat like few other materials can. Its key advantage comes from the 99.7% pure hexagonal boron nitride composition. This purity matters for consistent performance under harsh conditions. The material withstands temperatures up to 1800°C in inert atmospheres. It handles sudden temperature changes extremely well. This thermal shock resistance prevents cracking during rapid heating or cooling cycles.

You get excellent thermal conductivity from this crucible. Heat spreads evenly throughout the vessel. This avoids hot spots that could damage your materials. The material is also a strong electrical insulator. It won’t conduct electricity like graphite crucibles can. This electrical property is useful in many high-temperature processes.

Chemical inertness is another major benefit. The crucible resists attack from most molten metals, salts, and glasses. It doesn’t react with acidic or basic fluxes either. This inertness means your melt stays pure and uncontaminated. Crucible lifespan increases significantly.

The crucible surface is naturally non-wetting. Molten materials slide off easily after pouring. Little residue sticks to the walls. This makes cleaning straightforward and reuse practical. The smooth surface finish also helps with this release behavior. Machining from solid blocks ensures precise dimensions and reliable wall thickness. You get a crucible built for demanding lab or industrial work. Its combination of heat tolerance, stability, and non-reactivity makes it a top choice for melting, casting, and crystal growth applications.

Applications of High Temperature Resistant 99.7% Boron Nitride Bn Ceramic Crucible

High temperature resistant 99.7% Boron Nitride (BN) ceramic crucibles are essential tools. They handle extreme heat reliably. These crucibles resist temperatures up to 2100°C in inert atmospheres. They work well in vacuum too. Their purity is very high at 99.7%. This minimizes contamination risks. Sensitive materials stay pure during processing.

These crucibles show excellent thermal shock resistance. You can heat them rapidly. You can cool them rapidly. They resist cracking. This saves time in labs and factories. Downtime is reduced.

Chemical inertness is a major benefit. Molten metals do not wet the BN surface. Slag does not stick easily. This makes pouring easier. Crucible life is extended. You get more uses per crucible. Handling aggressive salts and fluxes is possible. Corrosion is minimal.

Applications are widespread. Crystal growth uses BN crucibles heavily. Sapphire crystals grow well inside them. Semiconductor processing relies on their purity. Evaporating metals like aluminum or gold happens cleanly. Vapor deposition processes benefit.

Metallurgy needs these crucibles. Melting reactive metals like titanium or zirconium is safer. Handling molten aluminum or its alloys works well. Flux refining processes use them. The crucibles withstand the harsh conditions.

5 FAQs of High Temperature Resistant 99.7% Boron Nitride Bn Ceramic Crucible

What is a boron nitride ceramic crucible?
This crucible holds molten metals or chemicals at extreme heat. Boron nitride ceramic is the material. It withstands temperatures most ceramics cannot handle. It’s ideal for demanding lab work or industrial processes.

How hot can this crucible get?
It handles temperatures up to 2100°C (3812°F) in inert gas or vacuum. In air, the safe limit is lower, around 900°C (1652°F). This high temperature resistance is its main advantage.

Why is 99.7% purity important?
Higher purity means fewer impurities. Impurities weaken the crucible over time. They can also contaminate your materials inside. 99.7% BN ensures strength and keeps your melts cleaner.

What can I use this crucible for?
Use it for melting precious metals like gold or platinum. Use it for processing semiconductor materials. Use it for growing crystals. It works well with corrosive salts and reactive metals. Its non-wetting surface helps pour melts cleanly.

How do I clean and care for it?
Handle it carefully. Boron nitride is strong but brittle. Avoid impacts. Clean it with hot water and a mild detergent. Avoid harsh acids or alkalis. For stubborn residue, use fine sandpaper gently. Dry it thoroughly before reuse. Store it in a dry place.
