Specification of High Pure Refractory 99% Corundum Sagger Alumina Crucible Boat Al2O3 Ceramic Parts for Gold Silver Aluminum Melting

This alumina crucible watercraft manages demanding steel melting tasks. It’s built for gold, silver, aluminum, and comparable high-temperature products. The key is its purity. It uses 99% Al2O3 diamond. This high-purity alumina supplies impressive efficiency. It resists severe warmth quite possibly. Expect trusted service as much as 1750 ° C (3182 ° F). Short bursts can get to also greater.

Thermal shock is a major problem for crucibles. This watercraft manages sudden temperature level modifications effectively. It will not fracture quickly when heated or cooled down quickly. This toughness indicates a much longer life expectancy. You get more thaws from each item. That saves money in time.

The product density is high. This gives the boat superb strength. It resists physical damage throughout handling. It likewise battles chemical strike from liquified metals and slags. This keeps your melt pure. Contamination dangers are reduced. Your rare-earth elements remain clean.

Its form is a flat-bottomed boat or sagger. This style optimizes surface get in touch with. Warmth transfers successfully right into your steel fee. Loading and pouring ended up being less complex jobs. Requirement sizes are available. Usual options are 100x50x25mm or 150x75x30mm. Other dimensions can be made. Custom forms are possible as well.

This crucible works in several heater types. Electric kilns, gas heating systems, induction arrangements– it fits. Its high pureness makes it inert. Reactions with your melt are marginal. This is crucial for exact alloying. It guarantees constant results every single time.

Contrasted to graphite or clay-graphite options, this alumina watercraft lasts longer. It holds up against a lot higher temperature levels. Chemical resistance is much remarkable. It’s the expert option for significant melting job. Performance warrants the financial investment.

Applications of High Pure Refractory 99% Corundum Sagger Alumina Crucible Boat Al2O3 Ceramic Parts for Gold Silver Aluminum Melting

Metal melting requires difficult containers. Regular pots fall short at high temperatures. They fracture or leak. High purity corundum sagger alumina crucibles solve this. They manage severe warmth well. These ceramic parts are made from 99% pure Al2O3. This pureness is vital. It makes the product extremely stable. It resists chemical attack. Molten silver or gold won’t react with it. Your thaw remains pure. Contamination damages rare-earth elements. These crucibles avoid that.

Thermal shock is a large problem. Heating and cooling fast breaks ceramics. This alumina manages it. The boat shape is important. Saggers hold numerous items. They move quickly in and out of heating systems. Crucibles hold molten metal directly. Both kinds are vital. They operate in kilns, induction heating systems, lab ovens. Security is important. The ceramic will not warp. It maintains its form cycle after cycle. This means trustworthy performance. You obtain constant results.

The high alumina content offers stamina. These parts won’t fracture under load. They last much longer than cheaper alternatives. Less downtime saves cash. Replacement expenses drop. Performance boosts. Pure alumina likewise means no unwanted additions. No silica or other changes. Absolutely nothing leakages into your thaw. Gold maintains its shade. Silver remains bright. Light weight aluminum pureness is vital for spreading. These ceramics make certain that. Jewelers utilize them for little gold batches. Factories use bigger saggers for light weight aluminum. Labs depend on them for accurate experiments. They are crucial for clean, high-temperature job.

5 FAQs of High Pure Refractory 99% Corundum Sagger Alumina Crucible Boat Al2O3 Ceramic Parts for Gold Silver Aluminum Melting

High Purity Refractory 99% Corundum Sagger Alumina Crucible Boat Al2O3 Ceramic Parts for Gold Silver Aluminum Melting – Key Questions Answered

What makes this crucible different?
It uses 99% pure alumina (Al2O3). This high purity matters. It prevents contamination of your melted metals like gold, silver, or aluminum. Impurities won’t get into your melt.

How hot can it go?
These crucibles handle extreme heat very well. They work reliably up to 1750°C (3182°F). That’s hot enough for melting gold, silver, platinum, and aluminum. They won’t soften or break down at normal melting temperatures.

Will it crack from sudden temperature changes?
Thermal shock resistance is good. You can heat it up fast. You can cool it down fast. It handles rapid temperature swings common in melting labs. It won’t crack easily like cheaper materials.

How do I clean it?
Cleaning is straightforward after use. Let the crucible cool completely first. Then remove any leftover metal slag or residue. Use basic tools like a chisel or hammer for stubborn bits. Avoid harsh chemicals unless necessary. A simple water rinse often works fine.

How long will it last?
Lifespan depends on your specific use. Factors include peak temperature reached, melting cycles, and the metals melted. With careful handling and avoiding physical damage, expect many uses. It lasts much longer than graphite or lower purity ceramics.
