This ensures high purity and security. It withstands chemical corrosion. It functions well in melting gold, platinum, silver, and similar steels. The alumina ceramic structure protects against contamination. This keeps melted steels pure. The crucible’s thickness is high. This minimizes porosity. It quits liquified steel from soaking into the ceramic. The crucible lasts much longer as a result of this.

Thermal shock resistance is strong. It takes care of quick temperature level adjustments. The dense framework prevents fractures. This is essential for repeated heating and cooling down cycles. The crucible’s shape is cylindrical. The layout sustains also heat circulation. This avoids locations. Thawing efficiency enhances. The leading diameter is broader than the base. This makes putting melted steel easier.

The crucible is available in several dimensions. Common elevations vary from 50mm to 200mm. Internal sizes range 30mm and 150mm. Wall density corresponds. This makes certain architectural toughness. The surface area is smooth. This simplifies cleansing after use. Residual metal or slag removes conveniently.

Chemical security is superb. It resists acids and antacids. This fits rough commercial settings. Oxidation resistance is high. This stops destruction at severe heat. The crucible operates in electric furnaces, gas heating systems, and induction heaters. It fits conventional lab and industrial arrangements.

Mechanical toughness is superior. The crucible stays undamaged under hefty tons. It resists abrasion throughout mixing or taking care of. The material stays non-reactive. This prevents unwanted chain reaction with molten metals.

Correct use expands life-span. Avoid sudden temperature changes when heating or cooling. Preheat the crucible gradually prior to high-temperature use. Store it in a dry location. Wetness weakens ceramic materials in time. Tidy it after each usage. Remove any type of leftover residues. This prevents buildup.

Applications include steel spreading, laboratory experiments, and fashion jewelry production. It serves small workshops and big factories. The crucible is reusable. This reduces long-lasting expenses. Performance remains regular over numerous cycles.

5 FAQs of 1500-1800C High Temperature 99 Al2o3 Alumina Ceramic crucible Cup For Melting Gold

What is the maximum temperature this crucible can handle. The crucible works in temperatures from 1500°C to 1800°C. It stays stable under heat. This makes it suitable for melting gold. The material resists cracking even with rapid temperature changes. Use it within this range for best results. Do not exceed 1800°C. Prolonged use above this limit may damage it.

Why is the crucible made of 99% alumina. High-purity alumina ensures better performance. It resists chemical reactions. This stops impurities from mixing with melted gold. The material also handles thermal stress well. Lower-purity ceramics crack faster. The 99% Al2O3 structure keeps the crucible strong over time.

How long does the crucible last. Lifespan depends on usage conditions. Regular use at 1700°C may last months. Frequent heating above 1750°C shortens it. Proper care extends durability. Avoid sudden cooling after heating. Let it cool slowly. Check for cracks before reuse. Replace it if visible damage appears.

Is the crucible safe for melting pure gold. Yes. The alumina material does not react with gold. No contamination occurs during melting. The surface stays smooth. This prevents gold loss. Clean the crucible before first use. Remove dust or residues. This ensures pure results.

How to maintain the crucible. Store it in a dry place. Moisture weakens the material. Avoid hitting hard surfaces. Thermal shock harms it. Heat it gradually. Do not overload with material. Follow weight limits. Clean after each use. Use soft tools to remove residues. Inspect for wear regularly.
