Overview of Mullite Crucible
Mullite crucibles are made from a high-performance ceramic material composed primarily of alumina (Al₂O₃) and silica (SiO₂). Known for their excellent thermal stability and mechanical strength, mullite crucibles are widely used in high-temperature applications such as melting metals, glass, and ceramics. They offer superior resistance to thermal shock and chemical attack, making them indispensable in both laboratory and industrial settings.
Features of Mullite Crucible
Thermal Shock Resistance: Exceptional ability to withstand rapid temperature changes without cracking.
High Mechanical Strength: Strong and durable, even at elevated temperatures.
Chemical Stability: Resistant to most chemicals, ensuring minimal contamination during processes.
Temperature Range: Can operate effectively at temperatures up to 1650°C.
Low Thermal Expansion: Minimal expansion or contraction with temperature changes, ensuring dimensional stability.
Non-Reactive: Does not react with the materials being processed, preserving sample purity.
Versatility: Suitable for a wide range of applications including metallurgy, glass manufacturing, and laboratory experiments.

Specifications of Graphite crucible With 27cm Diameter And 30 Cm Heigh Graphite-crucibl
Graphite Crucible– 27 cm Size × 30 cm Height
High-Purity Building and construction
This graphite crucible is made from high-purity synthetic graphite. The product offers superb thermal security and solid resistance to chemical corrosion. It manages aggressive environments without damaging down or responding with the majority of molten steels.
Accurate Dimensions
The crucible determines 27 centimeters in size and 30 centimeters in elevation . These measurements provide ample ability for melting, spreading, or holding large volumes of product. The constant wall surface thickness guarantees even warmth circulation and reduces the threat of breaking during fast temperature adjustments.
Thermal Efficiency
Graphite conducts warm extremely well. This crucible heats up promptly and keeps stable temperature levels throughout its entire surface. It works accurately at temperature levels approximately 3000 ° C in inert ambiences. Individuals can depend on it for repeated heating and cooling cycles without substantial wear.
Resilience and Durability
The dense framework of the graphite resists disintegration and thermal shock. This makes the crucible suitable for lasting industrial use. It stands up well under mechanical tension and maintains its form in time. Proper handling prolongs its life span even additionally.
Typical Applications
This dimension is ideal for factories, labs, and steel refining procedures. It works well with aluminum, copper, gold, silver, and other non-ferrous metals. Researchers and specialists likewise use it for high-temperature sample prep work and ash screening.
Taking care of Notes
Always pre-heat the crucible gradually before complete usage. Stay clear of sudden temperature level changes. Usage clean, completely dry devices when loading or eliminating materials. Store it in a dry area to prevent dampness absorption, which can weaken the structure throughout heating.

Applications of Graphite crucible With 27cm Diameter And 30 Cm Heigh Graphite-crucibl
Applications of 27cm Diameter × 30cm Height Graphite Crucible
Steel Melting and Spreading
This graphite crucible holds up well under extreme warmth. It functions excellent for melting metals like gold, silver, copper, aluminum, and brass. Its plus size– 27 centimeters broad and 30 cm tall– lets you thaw larger sets in one go. Factories and tiny workshops use it frequently since it warms equally and lasts a very long time.
Warm Treatment Processes
The crucible is additionally made use of in warmth treatment. You can place steel components inside and heat them to high temperatures without deforming or fracturing the container. Graphite deals with thermal shock much better than the majority of products. That makes this crucible trusted for duplicated home heating and cooling down cycles.
Research Laboratory and Research Usage
Labs pick this size when they need to process bigger samples. It functions well for ash testing, example blend, and high-temperature reactions. The pure graphite product does not react with most chemicals. This maintains test results tidy and accurate.
Glass and Ceramic Manufacturing
Musicians and producers use the crucible to thaw glass or prepare ceramic glazes. Its smooth internal surface helps protect against contamination. The tall form gives enough room for gurgling or frothing materials without spilling over.
Reusing and Scrap Healing
Scrap steel recyclers rely upon this crucible to recoup valuable steels from waste. It withstands misuse and frequent usage. Also after numerous thaws, it keeps its form and strength.
Why this size matters
The 27 centimeters size uses a large base for steady placement in furnaces. The 30 centimeters elevation offers lots of area over the melt line. This lowers spilling and makes putting safer. With each other, these measurements match both industrial work and thorough craft work.

5 FAQs of Graphite crucible With 27cm Diameter And 30 Cm Heigh Graphite-crucibl
Frequently Asked Questions About 27cm Diameter × 30cm Height Graphite Crucibles
What is this graphite crucible used for?
This graphite crucible holds and melts metals at very high temperatures. It works well for melting gold, silver, copper, aluminum, and other non-ferrous metals. Foundries, jewelers, and labs use it because it handles heat evenly and resists thermal shock.
Why choose graphite over other materials?
Graphite stays strong even when heated past 2000°C. It conducts heat quickly and spreads it evenly. This helps melt metal faster and more uniformly. Graphite also resists chemical reactions with most molten metals, so your material stays clean.
How long does this crucible last?
Lifespan depends on how often you use it and how you handle it. With proper care—like slow heating, avoiding sudden temperature changes, and gentle handling—it can last many melts. Always let it cool naturally after use. Do not drop or strike it, as graphite is brittle.
Can I use this crucible in any furnace?
Yes, as long as your furnace reaches the needed temperature and fits the crucible size. The outside measures 27cm wide and 30cm tall, so check your furnace chamber space first. Make sure there’s room for safe placement and removal with tongs.
How do I prepare a new crucible before first use?
Heat it slowly in the furnace to about 200–300°C for one hour. This removes moisture. Then raise the temperature gradually to 600–800°C and hold for another hour. This “seasons” the crucible and helps prevent cracks during actual melting. Never add cold metal to a hot crucible—it can cause breakage.
