Specification of 1500-1800C High Temperature 99 Al2o3 Alumina Ceramic Crucible For Melting Gold

This crucible handles extreme warmth. It’s made of 99% pure alumina ceramic. This product is extremely strong. It works perfectly from 1500 ° C to 1800 ° C. You require this for melting gold. Gold melts around 1064 ° C. This crucible provides you a lot of extra warmth capacity. Safety issues. The crucible will not fracture unexpectedly. It handles temperature level adjustments well. You heat it rapid or amazing it down quick. This crucible remains reputable.

Toughness is crucial. Pure alumina is really hard. It withstands wear. It deals with chemical assault. Molten gold is hostile. This product doesn’t respond a lot. Your gold remains pure. You stay clear of contamination. Crucible life is longer. You save money over time. You replace crucibles much less usually.

The surface is really smooth. This is essential. Molten steel doesn’t stick. You put out every drop. Cleansing is easy. You obtain efficient gold recovery. No product sticks within. You lose much less precious metal.

Usual sizes exist. You find them easily. Common capabilities are 10ml, 20ml, 50ml, 100ml. Larger sizes like 200ml or 500ml are available also. You pick the size for your task. Small amounts need tiny crucibles. Larger sets require bigger ones. The form is standard. It fits most heaters.

This crucible matches many jobs. Melting gold is the major usage. Refining gold functions well. Alloying gold with various other metals is feasible. Testing gold purity occurs frequently. Laboratory job uses these crucibles as well. They are important devices. Professionals count on them daily. Efficiency corresponds. Outcomes are trustworthy.

Applications of 1500-1800C High Temperature 99 Al2o3 Alumina Ceramic Crucible For Melting Gold

This crucible manages severe warm melting gold. It’s made from 99% alumina ceramic. This product is Al2O3. Pure alumina is key. It endures temperatures from 1500 ° C to 1800 ° C. Gold thaws around 1064 ° C. This crucible runs far above that factor. It provides a big safety and security margin. Crucibles crack if as well close to their restriction. This avoids that threat.

The high purity issues. Impurities infect molten gold. This crucible maintains the gold tidy. Its 99% Al2O3 make-up minimizes reactions. Gold stays pure. This is important for top quality jewelry or investment bars. Contamination damages value.

Longevity is an additional benefit. Alumina ceramic is extremely tough. It resists wear throughout mixing or putting. It deals with duplicated heating and cooling down cycles well. Thermal shock resistance is good. Abrupt temperature level modifications trigger splits. This crucible manages that stress and anxiety better than less costly materials. It lasts much longer. This saves money gradually.

Use calls for care. Preheat the crucible gradually. Prevent sudden temperature leaps. Place it firmly in the heater. Usage correct tongs for managing. Never place cool metal into hot liquified gold. This causes spilling. It threatens. It can likewise fracture the crucible. Tidy it after each use. Get rid of slag carefully. Avoid rough influences. Store it securely. Proper handling expands its life dramatically. This crucible is a reputable device for severe gold melting.

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

What’s the max temperature this crucible handles?
It safely handles 1800°C. This is its continuous working limit. Short spikes near 1850°C might be okay. Do not exceed 1850°C. Going higher risks cracking the crucible.

Why pick alumina ceramic for melting gold?
Alumina ceramic resists gold attack very well. Pure gold won’t stick to it. It won’t contaminate your melt. Alumina stays strong at high heat. It beats many metals and other ceramics for pure gold work. Its high purity matters.

Can I use flux inside it?
Yes, you can use common gold fluxes. Borax is fine. Avoid very aggressive fluxes. Some strong fluxes might slowly damage the alumina surface over many uses. Check your flux type. Test it first if unsure.

Does it handle sudden temperature changes?
It handles thermal shock better than many ceramics. Still, avoid extreme shocks. Don’t plunge a hot crucible into cold water. Let it cool down slowly inside the furnace. Pre-heat it gradually before each melt. This prevents cracks.

How do I clean it after melting?
Let it cool completely first. Tap out leftover metal carefully. Use a soft brush for loose debris. Soak it in dilute nitric acid for stuck gold residue. Rinse it very well with clean water afterward. Dry it fully before reheating. Avoid harsh abrasives.
