Spec of Refractory Diamond 99% Alumina Melting Ceramic Crucibles Dish Recipe with Lid for Heater

These crucibles are for high-temperature heater work. They are made from pure diamond. This material is 99% alumina. That purity offers superb performance. The crucibles stand up to extremely high heat. They take care of temperatures approximately 1750 ° C. This is good for thawing metals, alloys, and glass. The dense framework stops leakages. It also quits chemicals from assaulting the crucible. This implies longer life and cleaner thaws.

Thermal shock resistance is solid. The crucible deals with unexpected temperature adjustments well. This is essential for repeated home heating and cooling cycles. It decreases splitting danger. The crucibles come with a coordinating lid. The cover fits well. It assists regulate the thaw ambience. It additionally decreases warmth loss and product sprinkle.

Various sizes are available. Common capabilities are 50ml, 100ml, 250ml, 500ml. Larger sizes exist also. Pick the dimension matching your heating system and thaw quantity. The crucibles are usually white or off-white. This color comes from the pure alumina. Measurements differ by ability. External diameter, elevation, and wall surface density modification. Inspect the particular size graph.

The material is extremely hard. It is likewise fragile. Deal with the crucibles very carefully. Prevent impacts or decreases. Preheat brand-new crucibles gradually. This removes any kind of dampness. It avoids thermal shock damage. Never warm a vacant crucible to its optimum temperature level. This can create damages. Constantly position the crucible on an appropriate heating system rack. Do not establish it straight on the furnace flooring. Suit the crucible size to your heater chamber. Allow space for warm circulation.

Applications of Refractory Corundum 99% Alumina Melting Ceramic Crucibles Bowl Dish with Lid for Furnace

Refractory diamond crucibles made with 99% alumina are essential tools for severe heat. These ceramic meals deal with incredibly tough jobs. They withstand temperature levels soaring up to 1800 ° C. This makes them ideal for thawing steels and alloys. Factories depend on them continuously. They thaw iron, steel, brass, bronze, and precious metals like silver and gold. The crucibles do not crack quickly under sudden temperature level adjustments. This thermal shock resistance is essential for repeated heating and cooling cycles.

Products science labs depend upon these crucibles. Scientists utilize them to prepare special ceramics, glass batches, and progressed inorganic products. The high-purity alumina ensures marginal contamination. This pureness is vital for precise experiments and regular results. The product withstands chemical strike from numerous molten substances. Changes and slags won’t easily harm the crucible walls. This chemical inertness secures your thaw.

These crucibles are extremely sturdy. They last much longer than less costly alternatives. This decreases replacement prices and heater downtime considerably. Their design advertises efficient warm transfer inside your heater. The consisted of cover is important. It assists manage the melting ambience, reduces warmth loss, and avoids material splashing or dissipation. Safety boosts with the lid in position.

Industrial warm treatment procedures use them for calcining powders or sintering elements. Jewelers locate them essential for casting detailed pieces. Any type of application requiring a reliable, high-temperature container benefits from these crucibles. They are the workhorses for requiring thermal procedures. Pick them for regular efficiency under attack.

5 FAQs of Refractory Corundum 99% Alumina Melting Ceramic Crucibles Bowl Dish with Lid for Furnace

What temperature can these crucibles handle?
They withstand temperatures up to 1800°C (3272°F). This is their maximum safe operating limit. Do not exceed it. The crucible could crack or fail.

How long do these crucibles last?
Lifespan varies greatly. It depends on the temperature used, how often you heat and cool them, and what materials you melt inside. Gentle handling and avoiding thermal shock helps them last longer. Expect multiple uses under good conditions.

What materials can I melt safely?
They work well with most metals, alloys, and oxides. The 99% alumina resists acids and alkalis. Avoid materials containing fluorides or strong alkalis like sodium hydroxide. These chemicals attack the alumina quickly.

Can I heat them up or cool them down fast?
No. Avoid rapid temperature changes. Thermal shock can crack them. Heat the crucible slowly to your working temperature. Let it cool down slowly inside the furnace after use. Sudden cooling with air or water is bad.

Why is the lid important?
The lid traps heat inside the crucible. This makes melting more efficient. It also protects your melt from furnace atmosphere contamination. It prevents material splashing out. Always use the lid during melting.
