Specification of Aluminum Oxide Gold Melting 99 Al2O3 Alumina Ceramic Fire Assay Crucible for Laboratory test

This crucible melts gold examples for research laboratory fire assay screening. It’s made from premium alumina ceramic. The product is 99% pure light weight aluminum oxide (Al2O3). This high purity is vital. It stops contamination of your useful gold samples during intense heating. Impurities might ruin your examination outcomes.

The alumina ceramic withstands extreme temperatures. It handles continual consume to 1750 ° C (3182 ° F). This is hotter than a lot of gold melting calls for. You obtain a big safety and security margin. The material additionally stands up to thermal shock quite possibly. Crucibles will not crack quickly when warmed or cooled down rapidly. This resilience saves money and avoids fell short examinations.

Its thickness is high, around 3.9 g/cm TWO. This dense framework makes the crucible exceptionally strong. It stands up to wear from duplicated mixing and putting of liquified metal. The crucible will not chip or shed particles into your melt. Taste pureness stays intact.

Chemical resistance is outstanding. The crucible takes on solid acids and bases. It does not react with fluxes or litharge used in fire assay treatments. Your melts remain clean. The smooth surface area coating helps as well. Molten steel flows out easily without sticking. Cleanup is less complex.

These crucibles are essential for accurate precious metal analysis. Labs trust them for trusted gold, silver, and PGM screening. Constant performance test after test matters. We ensure tight quality control. Every batch fulfills rigorous specifications.

Applications of Aluminum Oxide Gold Melting 99 Al2O3 Alumina Ceramic Fire Assay Crucible for Laboratory test

Light weight aluminum oxide crucibles are crucial tools for gold screening laboratories. These crucibles contain 99% Al2O3 alumina ceramic. This high purity matters. It protects against undesirable steels from infecting your gold example during intense warm. Accuracy is essential in fire assay work. Contamination damages results.

These crucibles handle extreme conditions. They hold up against temperatures over 1700 ° C easily. Fire assay calls for melting samples at very high heat. Conventional materials fail. Alumina ceramic survives. It likewise takes care of abrupt temperature adjustments well. Thermal shock resistance avoids splitting when home heating or cooling down swiftly. Lab procedures usually include quick temperature level changes.

Sturdiness is one more crucial advantage. Alumina ceramic is really hard. It stands up to damage from flux products and repeated use. Fluxes like salt carbonate or borax are destructive. The crucible material battles this corrosion. Low porosity is very important. It quits molten metals or changes from saturating right into the crucible wall surfaces. This keeps your sample undamaged and avoids worldly loss.

Utilizing 99% Al2O3 crucibles means reliable performance. They provide constant results test after test. Labs trust them for precise gold and precious metal analysis. Their toughness enables several usages. This conserves cash gradually. You prevent constant replacements. The crucible remains secure chemically. It doesn’t react with the sample or fluxes. Stability guarantees your evaluation mirrors the true steel web content.

5 FAQs of Aluminum Oxide Gold Melting 99 Al2O3 Alumina Ceramic Fire Assay Crucible for Laboratory test

Here are 5 FAQs about our Aluminum Oxide Gold Melting Crucible:

What is this crucible used for?
This crucible melts gold samples. It is for fire assay testing in labs. You use it to prepare precious metal samples for analysis. The crucible holds molten gold safely.

Why is it made from alumina ceramic?
Alumina ceramic (Al2O3) is very hard. It resists extreme heat well. Crucibles need this for melting gold. Gold melts at very high temperatures. Alumina ceramic handles this easily. It also resists chemical attack. Molten fluxes won’t damage it quickly. This makes the crucible last longer.

How hot can it get?
This 99% Al2O3 crucible withstands very high temperatures. Its maximum working temperature is 1750°C (3182°F). This is hotter than gold melts. It is safe for standard fire assay procedures. Avoid sudden temperature changes. Thermal shock can crack it.

What sizes are available?
We offer several standard sizes. Common capacities are 5ml, 10ml, 15ml, 20ml, 30ml, and 50ml. The size depends on your sample amount. Choose the capacity fitting your lab’s typical gold sample weight. Custom sizes might be possible.

How do I clean it after use?
Cleaning is important. Remove all slag and residue completely. First, let the crucible cool down slowly. Never quench hot crucibles in water. Use mechanical methods. Gently scrape out cooled material. A small brush helps remove fine particles. Avoid harsh chemicals unless necessary. Inspect for cracks before reuse.
