Specification of Graphite glassy carbon crucible

Graphite Glassy Carbon Crucible– Technical Specification

Product Structure

This crucible is made from high-purity graphite and glazed carbon. The blend gives it solid resistance to heat and chemicals. It consists of over 99.9% carbon, which makes sure marginal contamination during high-temperature procedures.

Temperature Resistance

The crucible works safely approximately 2,500 ° C in inert or vacuum cleaner environments. It keeps its form and toughness even under extreme thermal stress and anxiety. Fast heating or air conditioning will not create fractures or breakage.

Chemical Stability

Strong acids, alkalis, and molten steels do not quickly respond with this product. It resists corrosion from the majority of hostile substances utilized in labs and sector. Nonetheless, prevent using it with strong oxidizing agents like nitric acid or oxygen-rich environments over 450 ° C.

Physical Features

The crucible has a smooth, non-porous surface. This assists prevent example absorption and makes cleaning much easier. Its thickness ranges from 1.65 to 1.75 g/cm THREE. Thermal conductivity is high, so heat spreads evenly throughout the crucible. Coefficient of thermal growth is reduced, which includes in its thermal shock resistance.

Measurements and Resistance

Standard dimensions range from 10 mL to 500 mL capability. Personalized shapes and quantities are likewise readily available. Wall thickness corresponds, with dimensional resistance within ± 0.2 mm. Each unit is checked for harmony prior to delivery.

Applications

This crucible fits jobs like melting metals, ash testing, crystal development, and high-temperature sintering. It is commonly used in research study labs, metallurgy, and semiconductor production. Its purity and stability make it ideal for delicate analytical work.

Dealing with Notes

Constantly handle with tidy tools to stay clear of surface area damage. Shop in a dry area far from dirt and moisture. Do not subject it to mechanical influence– it is tough but fragile. Usage appropriate heater settings to match its operating limits.

High-Temperature Product Handling

Graphite glassy carbon crucibles take care of extreme warm without breaking down. They function well in melting metals like gold, silver, platinum, and other valuable alloys. Their structure remains steady also above 2000 ° C. This makes them ideal for foundries and fashion jewelry workshops where pureness and temperature control matter.

Crystal Growth and Semiconductor Manufacturing

These crucibles are used to expand top notch single crystals, such as sapphire or silicon carbide. The material does not respond with molten compounds, so it maintains the crystal free from contamination. In semiconductor manufacturing, also little contaminations can ruin a batch. Graphite glazed carbon prevents this risk and supports regular outcomes.

Research Study and Research Laboratory Usage

Labs depend on these crucibles for example preparation and thermal evaluation. Scientists use them in X-ray fluorescence (XRF) and inductively coupled plasma (ICP) testing. The crucibles withstand chemical strike from acids, bases, and molten salts. They additionally release extremely few fragments during home heating, which helps preserve precise examination information.

Specialized Glass and Ceramic Manufacturing

When making optical glass or advanced ceramics, makers need containers that will not introduce flaws. Graphite glazed carbon crucibles meet this requirement. They do not flake or wear away under duplicated home heating cycles. Their smooth inner surface area avoids unwanted nucleation websites, bring about clearer glass and stronger ceramic parts.

Vacuum and Inert Ambience Processes

These crucibles carry out dependably inside vacuum furnaces or argon-filled chambers. They do not outgas unsafe vapors, which is essential when dealing with responsive metals like titanium or zirconium. Their reduced porosity stops gases from leaking with, maintaining the internal setting clean and controlled.

5 FAQs of Graphite glassy carbon crucible

Frequently Asked Questions About Graphite Glassy Carbon Crucibles

What is a graphite glassy carbon crucible?

A graphite glassy carbon crucible is a special container used for melting or heating materials at very high temperatures. It combines the strength of graphite with the smooth, non-porous surface of glassy carbon. This makes it resistant to thermal shock and chemical corrosion.

Why choose this crucible over others?

This crucible handles extreme heat better than many metal or ceramic options. It does not react easily with most chemicals. Its surface stays clean and smooth, which helps prevent contamination during sensitive processes like crystal growth or metal purification.

Can it be used in air at high temperatures?

No. Graphite oxidizes when exposed to air above 450°C (842°F). For best results, use the crucible in an inert atmosphere like argon or nitrogen, or under vacuum conditions. This protects it from burning or degrading.

How long does it last?

Lifespan depends on how you use it. If you avoid sudden temperature changes, mechanical stress, and exposure to oxygen at high heat, the crucible can last many cycles. Always follow recommended heating and cooling rates to extend its service life.

Is it easy to clean?

Yes. Because the surface is non-porous and chemically stable, residues do not stick strongly. Most contaminants can be removed by gentle brushing or rinsing with appropriate solvents. Avoid abrasive tools that might scratch or damage the surface.
