Specifications of Crystal sintered graphite crucible

Crystal Sintered Graphite Crucible– Key Specifications

Material Make-up

This crucible is made from high-purity sintered graphite. The material consists of over 99.9% carbon. It has very reduced levels of ash and contaminations. This guarantees clean melting and very little contamination during high-temperature procedures.

Temperature Resistance

The crucible can deal with temperature levels as much as 3000 ° C in inert ambiences. In normal air, it remains stable as much as concerning 450 ° C. For best outcomes, use it in vacuum cleaner or argon settings when functioning over 600 ° C. This protects against oxidation and extends life span.

Density and Toughness

Its obvious thickness ranges from 1.70 to 1.85 g/cm SIX. The crucible reveals good mechanical toughness also at high warmth. It stands up to thermal shock well, which suggests it will not crack conveniently when heated or cooled promptly.

Dimensions and Tolerance

Requirement sizes vary from 50 mL to 5000 mL capacity. Wall surface thickness is usually between 5 mm and 15 mm, depending on dimension. All crucibles are machined to limited dimensional tolerances– normally within ± 0.5 mm– for consistent fit and performance.

Surface Complete

The inner surface is smooth and polished. This minimizes product sticking and makes cleansing much easier after use. The outer surface might be a little rougher but remains uniform and without cracks or pits.

Applications

This crucible functions well for melting steels like gold, silver, copper, and aluminum. It is also utilized in laboratory setups for example preparation, crystal growth, and high-temperature responses. Its purity and stability make it excellent for sensitive industrial and study jobs.

Applications of Crystal sintered graphite crucible

Applications of Crystal Sintered Graphite Crucibles

Metal Melting and Casting

Crystal sintered graphite crucibles are commonly used for melting and casting non-ferrous metals. These consist of light weight aluminum, copper, zinc, and precious metals like gold and silver. The crucibles handle high temperatures without breaking. Their thermal shock resistance ensures steady efficiency during repeated home heating and cooling cycles. Foundries and precious jewelry workshops rely on them for tidy, efficient thaws with minimal metal loss.

Heat Treatment Processes

These crucibles also serve well in heat therapy applications. They provide a stable setting for annealing, sintering, and various other regulated environment processes. Because graphite performs warmth uniformly, parts warmth uniformly. This decreases the risk of warping or irregular results. Industries such as aerospace and tool production utilize them to deal with tiny batches of vital elements.

Research Laboratory and Research Use

In research study laboratories, crystal sintered graphite crucibles sustain sample preparation and product testing. Researchers pick them for their purity and chemical inertness. They do not react with many liquified materials, which maintains examination results accurate. Universities and material scientific research centers commonly utilize these crucibles for experiments including high-temperature reactions or alloy development.

Specialized Glass and Ceramics Manufacturing

Glass and ceramic manufacturers make use of these crucibles to melt resources at severe temperature levels. The smooth internal surface area prevents contamination. It also makes it much easier to put out the liquified batch cleanly. Art glass studios and technical porcelains manufacturers worth this reliability for both small and pilot production runs.

Recycling Procedures

Metal recyclers rely on crystal sintered graphite crucibles to redeem scrap efficiently. The crucibles stand up to hostile slags and repeated use. They assist recoup high-purity metals from combined waste streams. This sustains cost-effective and eco-friendly reusing practices throughout the industry.

5 FAQs of Crystal sintered graphite crucible

Frequently Asked Questions About Crystal Sintered Graphite Crucibles

What is a crystal sintered graphite crucible?

A crystal sintered graphite crucible is made from high-purity graphite. It goes through a special sintering process that gives it a dense, strong structure. This type of crucible can handle very high temperatures without breaking down.

Why choose crystal sintered over regular graphite crucibles?

Crystal sintered crucibles have better thermal shock resistance. They also last longer and keep their shape under repeated heating and cooling. Regular graphite crucibles may crack or wear out faster in tough conditions.

What temperatures can it handle?

These crucibles work well up to 3000°C in inert atmospheres. In normal air, they are stable up to about 500°C. Always check your specific application environment before use.

Is it safe for melting metals?

Yes. Crystal sintered graphite crucibles are widely used for melting non-ferrous metals like gold, silver, copper, and aluminum. The material does not react easily with most molten metals, so it keeps your melt clean.

How do I care for my crucible?

Handle it gently to avoid cracks. Never cool it quickly with water after heating. Let it cool slowly in the furnace or on a heat-resistant surface. Store it in a dry place to prevent moisture absorption. Clean residue only after it has fully cooled, using soft tools to avoid scratching the surface.
