Specifications of High Purity Ceramic Crucibles Boron Nitride 99.7%

This high purity boron nitride ceramic crucible offers excellent performance. Its purity reaches 99.7%. This is very important for demanding applications. Impurities are extremely low. This ensures reliable results. The material handles extreme heat well. It withstands temperatures up to 2100°C in inert atmospheres. It works well up to 900°C in air. This makes it suitable for many high-temperature processes.

The crucible strongly resists chemical attack. It is not wet by molten metals. This includes aluminum, copper, and their alloys. It works with many salts and glasses too. This chemical inertness prevents contamination. Your materials stay pure. Thermal shock resistance is outstanding. You can heat it fast. You can cool it fast. It rarely cracks. This saves time and money.

Boron nitride has a hexagonal crystal structure. This makes it naturally slippery. Machining is easy. You get precise dimensions. Surface finishes are smooth. This minimizes sticking. The material is electrically insulating. This is useful in many lab and industrial settings. It provides good thermal conductivity too. Heat spreads evenly. Hot spots are reduced.

Different sizes and shapes are available. Common types include cylindrical and conical designs. Standard sizes meet most needs. Custom sizes are possible. The crucible works in vacuum furnaces. It works in inert gas furnaces. Common applications include metal melting. Crystal growth uses it. Powder metallurgy relies on it. High-purity material processing needs it. It replaces graphite crucibles where purity matters more. Handling is straightforward. Store it in a dry place. Avoid strong impacts. Clean it with appropriate methods.

Applications of High Purity Ceramic Crucibles Boron Nitride 99.7%

These boron nitride ceramic crucibles offer exceptional purity at 99.7%. This high purity is critical for demanding applications where even tiny contaminants ruin results. They handle extreme heat exceptionally well, maintaining strength and stability far beyond many other materials. Crucibles made from this material resist chemical attack from many molten metals, salts, and corrosive gases. This chemical inertness protects both the crucible and the material being processed.

Their non-wetting surface is a major advantage. Molten materials, especially reactive metals like aluminum, magnesium, or their alloys, do not stick to the crucible walls. This makes pouring much easier and cleaner. It also minimizes sample loss and simplifies crucible cleaning after use. You get more usable material and less downtime.

These properties make these crucibles essential tools in several high-tech fields. Semiconductor manufacturing relies on them for processes like vapor deposition and growing crystals. The extreme purity prevents silicon or gallium arsenide wafers from picking up unwanted impurities. Crystal growth for lasers, optics, and electronics frequently uses these crucibles. Metal casting operations, especially for reactive or high-purity alloys, benefit from the non-wetting surface and chemical resistance. Advanced ceramics sintering and powder metallurgy processes also use them to contain materials at very high temperatures without contamination. Handling molten salts, particularly in research or battery material development, is another common application. The crucibles withstand the aggressive environment reliably.

5 FAQs of High Purity Ceramic Crucibles Boron Nitride 99.7%

What makes boron nitride crucibles special?
They handle extreme heat. Boron nitride stays solid past 2000°C. It won’t crack when heated or cooled fast. This material resists chemical attack. Most molten metals won’t stick to it. It keeps your sample pure.

How hot can I safely use them?
Use them continuously up to 1800°C in air. Use them up to 2100°C in vacuum or inert gas. Don’t use them above these temperatures. Extreme heat damages the crucible over time. Check the maker’s exact specs for your model.

Why is 99.7% purity important?
High purity means fewer impurities. Impurities can contaminate your sample. This is critical for sensitive work. Examples include growing crystals or processing reactive metals. Lower purity crucibles risk ruining your material.

How do I handle these crucibles?
Handle them carefully. Boron nitride is brittle. Avoid dropping or hitting them. Use clean tools. Don’t contaminate the surface. Store them in a dry place. Keep them away from dust and dirt. Wear gloves to prevent skin oils.

What chemicals attack boron nitride?
Strong alkalis and acids damage it. Molten hydroxides are very bad. Avoid concentrated bases like lye. Avoid strong acids like sulfuric acid. It’s fine with most other chemicals and molten salts. Check chemical compatibility charts first.
