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 1500-1800C High Temperature 99 Isostatic Pressure Lab Al2o3 Alumina crucible Gold Melting crucible
High-Temperature 99% Alumina Crucible for Gold Melting
Material and Pureness
This crucible is made from 99% pure alumina (Al ₂ O SIX) . The product is developed using isostatic pushing , which provides it a very consistent structure. This process eliminates weak points and makes the crucible solid completely via.
Temperature level Resistance
It can deal with constant use at temperatures in between 1500 ° C and 1800 ° C . This makes it excellent for thawing gold, silver, platinum, and various other rare-earth elements. The high melting factor of alumina ensures the crucible stays stable also under extreme warm.
Layout and Resilience
The crucible has a smooth inner surface that lowers metal sticking. Its dense structure withstands thermal shock, so it will not split quickly when warmed or cooled rapidly. The wall surfaces are thick sufficient to supply lengthy service life but slim adequate to permit effective warmth transfer.
Applications
This crucible is constructed for research laboratory and small refining job . It works well in induction furnaces, gas-fired kilns, and electrical muffle heaters. Jewelers, refiners, and scientists utilize it for clean, contamination-free melting. Since it’s constructed from high-purity alumina, it won’t respond with liquified steels or add impurities to your batch.
Secret Includes
– 99% Al ₂ O six purity for chemical inertness
– Isostatic pushing for regular density and toughness
– Usable up to 1800 ° C without contortion
– Resistant to thermal shock and deterioration
– Smooth interior coating for easy putting and cleaning up
This crucible gives dependable performance in high-heat settings. It’s a relied on option for any individual that needs clean, specific melting of precious metals in a laboratory or workshop setting.

Applications of 1500-1800C High Temperature 99 Isostatic Pressure Lab Al2o3 Alumina crucible Gold Melting crucible
High-Temperature Alumina Crucible for Demanding Applications
Built for Extreme Warmth and Precision
This lab-grade alumina crucible is made from 99% pure light weight aluminum oxide. It uses isostatic pressing to make sure uniform density and strength. The outcome is a crucible that handles temperature levels from 1500 ° C to 1800 ° C without breaking or deforming.
Gold melting is one of its major usages. The high purity avoids contamination during rare-earth element refining. Also after duplicated home heating cycles, the crucible stays chemically inert. That implies your gold stays clean and pure.
It likewise works well in product research , specifically when testing porcelains, oxides, or rare-earth compounds. Labs rely upon it for sintering, calcining, and ash content analysis. Its smooth inner surface makes example recuperation easy and lowers worldly loss.
In industrial quality control , this crucible sustains consistent results. It withstands thermal shock better than standard porcelain or quartz ware. You can heat it quickly or cool it down without fear.
The isostatic stress procedure offers the crucible tight grain structure. This enhances mechanical strength and expands life span. Unlike cast or shaped versions, it has no vulnerable points or concealed pores.
Key features include:
– Secure performance up to 1800 ° C.
– Outstanding resistance to acids and molten metals.
– Reduced thermal expansion for reliable handling.
– Reusable after appropriate cleansing.
Whether you’re thawing tiny gold sets or running high-temp experiments, this alumina crucible delivers reputable efficiency. It satisfies the needs of both research study labs and small-scale refiners who require accuracy and durability.

5 FAQs of 1500-1800C High Temperature 99 Isostatic Pressure Lab Al2o3 Alumina crucible Gold Melting crucible
Frequently Asked Questions: 1500–1800°C High-Temperature 99% Isostatic Pressure Lab Al₂O₃ Alumina Crucible for Gold Melting
What is this crucible made of?
This crucible is made from 99% pure alumina (Al₂O₃). It is formed using isostatic pressing. This method gives the material high density and uniform structure. The result is a strong, durable crucible that resists cracking under extreme heat.
Why choose alumina for gold melting?
Alumina has excellent chemical stability. It does not react with molten gold or most precious metals. It also withstands temperatures up to 1800°C without deforming. This makes it ideal for clean, safe gold melting in lab or small-scale refining work.
Can it handle repeated heating and cooling?
Yes. Thanks to its high purity and dense structure, this crucible shows good thermal shock resistance. It can go through many heat-cool cycles without breaking—provided you heat and cool it slowly and evenly.
Is it suitable for other metals besides gold?
It works well with silver, platinum, palladium, and other noble metals. Avoid using it with strong alkalis, reactive metals like aluminum or titanium, or materials that form low-melting-point compounds with alumina. Always check compatibility before use.
How should I care for the crucible?
Let the crucible cool completely before cleaning. Remove residue gently with a soft brush or non-metallic scraper. Do not use water on a hot crucible. Store it in a dry place. Never subject it to sudden temperature changes or mechanical impact. Proper handling will extend its life significantly.
