Specifications of Anti-Corrosion Boron Nitride Bn Ceramic Rectangular Crucible

Specs of Anti-Corrosion Boron Nitride (BN) Ceramic Rectangular Crucible

Material and Structure

This crucible is made from high-purity hexagonal boron nitride (h-BN). The BN material is over 99%. It consists of no binders or additives. This gives the crucible excellent chemical inertness and thermal stability.

Dimensions and Forming

The crucible has a rectangle-shaped form with straight walls and a flat base. Criterion sizes consist of internal measurements such as 50 mm × 30 mm × 20 mm (L × W × H), however customized sizes are offered. Wall thickness ranges from 2 mm to 5 mm, depending upon the version.

Thermal Performance

It can run constantly at temperatures approximately 1000 ° C in air and up to 2000 ° C in inert atmospheres. The material reveals very low thermal development. It withstands thermal shock well, even throughout rapid home heating or cooling down cycles.

Chemical Resistance

Boron nitride is very resistant to rust. It does not respond with the majority of molten metals, including light weight aluminum, zinc, and copper. It additionally holds up against many acids, antacid, and slags. This makes it ideal for usage in aggressive chemical atmospheres.

Electrical and Mechanical Features

The crucible is an electrical insulator, also at heats. Its surface is smooth and non-wetting, which helps avoid product sticking. Though lightweight, it preserves great mechanical toughness under typical handling problems.

Surface End Up and Pureness

All surface areas are machined to a great coating. The inside is tidy and devoid of pores or fractures. This makes sure marginal contamination throughout high-temperature handling. The crucible fulfills stringent purity standards required in semiconductor, metallurgy, and lab applications.

Handling Notes

Although strong, the crucible is fragile. Prevent sharp influences or unexpected tension. Always make use of compatible devices when filling or removing materials. Shop in a completely dry place to preserve efficiency and durability.

Applications of Anti-Corrosion Boron Nitride Bn Ceramic Rectangular Crucible

High-Temperature Metal Thawing

Boron nitride crucibles take care of extreme heat without damaging down. They work well for melting reactive metals like titanium, zirconium, and unusual planet components. These steels strike most containers, however BN resists chain reactions. The rectangular shape gives a lot more useful room and fits much better in numerous heating systems.

Semiconductor and Crystal Development

In semiconductor manufacturing, purity matters a lot. BN crucibles do not launch impurities when warmed. This makes them optimal for expanding high-quality crystals such as gallium arsenide or sapphire. Their smooth surface helps control crystal development. The anti-corrosion attribute maintains the thaw clean from beginning to end.

Advanced Ceramics Handling

When making technical ceramics, products usually require to remain molten for extended periods. Standard crucibles might crack or leak under these conditions. BN ceramic crucibles remain stable. They stand up to thermal shock and do not react with ceramic powders or binders. Their rectangular style sustains also heating and much easier handling throughout filling and unloading.

Lab and Research Study Use

Scientists depend on BN crucibles for experiments entailing aggressive chemicals or high temperatures. The material does not contaminate examples. It also allows for duplicated usage without losing efficiency. Labs pick the rectangle-shaped version since it piles nicely and saves area in small stoves or handwear cover boxes.

Specialty Glass and Optical Products

Some optical glasses consist of fluorides or various other corrosive components. Common containers fail rapidly in these melts. BN crucibles stand up to such environments. They assist create clear, defect-free glass utilized in lenses, lasers, and fiber optics. The level sides of the rectangle-shaped shape make it simpler to keep an eye on the melt visually.

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

Frequently Asked Questions About Anti-Corrosion Boron Nitride (BN) Ceramic Rectangular Crucibles

What is a boron nitride ceramic crucible?

A boron nitride (BN) ceramic crucible is made from high-purity BN powder. It has a rectangular shape and resists corrosion from many molten metals and salts. This material stays stable at high temperatures and does not react easily with other substances.

Why choose BN over other crucible materials?

BN crucibles offer excellent thermal shock resistance and low wettability. They do not stick to most melts, which makes cleaning easier. Unlike graphite or alumina, BN does not contaminate sensitive materials during high-temperature processing.

What temperatures can this crucible handle?

This crucible works well up to 2,000°C in inert or vacuum environments. In air, its safe use limit is around 1,000°C because BN slowly oxidizes at higher temperatures. Always match the operating atmosphere to your temperature needs.

Is it safe for handling reactive metals?

Yes. BN is chemically inert to many reactive metals like titanium, zirconium, and rare earth elements. It also resists attack from molten salts and slags. That makes it ideal for research and production involving aggressive melts.

How should I handle and clean the crucible?

Handle the crucible gently—it is strong but brittle. Avoid sudden impacts or rapid temperature changes. After use, remove residues with soft brushes or ultrasonic cleaning in mild solvents. Do not use abrasive tools or strong acids that could damage the surface.
