Overview of Custom Shape Aluminum Nitride Alnceramic Crucible

Aluminum Nitride Ceramic is an advanced ceramic material with aluminum nitride as the main component. It has been widely used in electronics, optics, and mechanics due to its unique properties.

Features of Custom Shape Aluminum Nitride Alnceramic Crucible

High thermal conductivity: Aluminum nitride ceramics have relatively high thermal conductivity, usually between 170-260 W/m·K, which makes it an excellent heat dissipation material. It is especially suitable for electronic devices that require efficient heat dissipation, such as substrate materials for power semiconductor devices.

Good electrical insulation: Despite its high thermal conductivity, aluminum nitride ceramics are excellent insulators of electricity, which can effectively prevent current leakage and ensure the safe operation of electronic components.

Low dielectric constant and dielectric loss: These characteristics make aluminum nitride ceramics very suitable for use in high-frequency circuits because it can reduce energy loss during signal transmission.

High temperature resistance: Aluminum nitride ceramics can maintain structural stability and strength at extremely high temperatures. Its melting point is about 2800°C, so it is suitable for applications in high temperature environments.

Low thermal expansion coefficient: Compared with semiconductor materials such as silicon, aluminum nitride has a lower thermal expansion coefficient, which means it has better dimensional stability when the temperature changes, which helps improve packaging reliability.

Corrosion resistance: Aluminum nitride ceramics have good chemical stability to most molten metals and are not easily oxidized or corroded, allowing them to perform well in harsh environments.

High mechanical strength: Although not as hard as some other types of ceramic materials, aluminum nitride ceramics still provide enough mechanical strength to allow them to be used in many structural applications.

Specifications of Custom Shape Aluminum Nitride Alnceramic Crucible

Here are the specifications for custom shape aluminum nitride ceramic crucibles. Aluminum nitride ceramic offers high thermal conductivity and excellent electrical insulation. This material withstands extreme temperatures easily. Chemical resistance is strong against molten metals and corrosive chemicals. Low thermal expansion prevents cracking during rapid heating or cooling.

Purity levels reach 99% or higher. This ensures minimal contamination in sensitive processes. Thermal conductivity is typically 170-200 W/mK. That efficiently transfers heat where needed. Maximum use temperature is around 1800°C in inert atmospheres. Operating temperature in air is lower, about 1400°C.

We make crucibles in any shape you require. Common options include boats, trays, tubes, and special geometries. Tell us your specific dimensions. We handle inner diameter, outer diameter, height, wall thickness, and overall profile. Precision machining achieves tight tolerances on all features. Surface finishes are smooth. We polish to reduce sticking and aid cleaning.

These crucibles suit demanding applications. They work well in semiconductor crystal growth, metal evaporation, and high-temperature sintering. Aluminum nitride resists reaction with gallium arsenide and other compounds. Electrical properties make it ideal for electronic component processing. Mechanical strength supports repeated thermal cycling. Long service life lowers replacement costs.

Customization covers more than shape. We adjust purity grades for your budget and needs. Special surface treatments are available. Markings or identifiers can be added. Small batches or large production runs are possible. We discuss your exact requirements first. We then provide the crucible solution matching your process perfectly.

Applications of Custom Shape Aluminum Nitride Alnceramic Crucible

Custom shape aluminum nitride ceramic crucibles serve critical roles across demanding industries. Semiconductor manufacturing relies on them heavily. Chip makers need crucibles that take extreme heat without breaking down. AlN crucibles handle this easily. They also resist chemical attack from reactive melts. This keeps silicon wafers pure during processing. Crystal growth uses these crucibles too. Growing high-quality crystals like gallium arsenide demands stable, non-reactive containers. Aluminum nitride provides this. The crucible shape matters here. Custom designs fit specific crystal pulling equipment perfectly. This ensures precise temperature control.

Metal labs need them too. They handle reactive molten metals like aluminum or alloys. Ordinary crucibles fail quickly. AlN stands up to the corrosion. You melt materials inside without worrying about contamination. Crucibles shaped for particular furnaces or pouring methods boost efficiency. Pouring molten metal becomes safer and more controlled. Aerospace and research settings use custom AlN crucibles. Experiments often need unique sizes or designs. Maybe a researcher requires a special lid or an unusual base shape. Manufacturers can produce these. The material handles sudden temperature changes well. This is vital for testing new materials or processes. High-energy physics experiments sometimes use them also. They contain materials under intense conditions. The thermal stability and electrical insulation of AlN are key benefits here.
