Overview of Silicon Carbide Crucible

Silicon carbide (SiC) crucibles are advanced ceramic vessels known for their exceptional thermal conductivity, high strength, and resistance to thermal shock. These crucibles can withstand extreme temperatures up to 1600°C and are highly resistant to chemical attack, making them ideal for melting metals, alloys, and other materials in both laboratory and industrial settings.

Features of Silicon Carbide Crucible

High Thermal Conductivity: Efficient heat transfer ensures uniform heating and rapid temperature changes.

Thermal Shock Resistance: Can endure rapid temperature fluctuations without damage.

Chemical Inertness: Resistant to most acids and alkalis, minimizing contamination.

Temperature Range: Operates effectively at temperatures up to 1600°C.

Mechanical Strength: Extremely durable and strong, even under harsh conditions.

Non-Reactive: Does not react with the materials being processed, preserving sample purity.

Long Service Life: Durable construction ensures extended use and reliability.

Specification of 1Kg 2Kg 3Kg Graphite Crucible Filling Silicon Carbide Graphite Crucible

Graphite Crucible for High-Temperature Melting

Our graphite crucibles come in three standard sizes: 1kg, 2kg, and 3kg. Each crucible is made from high-purity graphite filled with silicon carbide. This combination gives the crucible excellent heat resistance and long service life.

Strong and Heat-Resistant Design

The silicon carbide filling strengthens the graphite structure. This makes the crucible more resistant to thermal shock and mechanical stress. It can handle repeated heating and cooling without cracking or breaking easily. The material also resists chemical corrosion from molten metals like aluminum, copper, brass, and zinc.

Consistent Performance

These crucibles heat up quickly and evenly. They maintain stable temperatures during melting operations. This helps produce consistent results batch after batch. The smooth inner surface reduces metal sticking and makes pouring easier.

Built for Real Workshop Use

We design these crucibles for everyday use in foundries, jewelry workshops, and small metal casting operations. The 1kg size works well for small jobs or testing. The 2kg and 3kg versions suit regular production needs. All sizes fit common furnace setups and lifting tools.

Quality You Can Trust

Every crucible goes through strict quality checks before shipping. We inspect for cracks, density issues, and surface defects. Only crucibles that meet our standards leave the factory. This ensures you get a reliable product every time.

Store your crucible in a dry place before use. Always preheat it slowly to avoid sudden temperature changes. With proper handling, it will deliver strong performance over many melting cycles.

Applications of 1kg, 2kg, and 3kg Graphite Crucibles Loaded With Silicon Carbide

High-Performance Melting for Small-Scale Operations

These graphite crucibles come in 1kg, 2kg, and 3kg dimensions. They are constructed with a special mix of graphite and silicon carbide. This mix gives them strong warmth resistance and long life. They function well in little factories, precious jewelry workshops, and study labs.

Thawing Rare-earth Elements
Artisans and jewelry experts usually use these crucibles to melt gold, silver, platinum, and other precious metals. The product takes care of heats without cracking. It also resists chain reactions, so the metal stays pure throughout melting.

Casting Non-Ferrous Alloys
Factories use them for aluminum, brass, bronze, and copper alloys. The crucibles heat up swiftly and keep temperature level constant. This aids produce constant spreadings with less defects. Their portable dimension fits most tiny induction or gas furnaces.

Research Laboratory and Educational Use
Schools and screening laboratories pick these crucibles for experiments and sample prep work. They are very easy to deal with and clean. Their reliability makes them optimal for repeated heating cycles in controlled settings.

Toughness You Can Count On
The silicon carbide layer shields the graphite core from oxidation and thermal shock. This suggests fewer replacements and reduced expenses with time. Each crucible is shaped for smooth putting and very little steel loss.

These crucibles suit anybody that needs trustworthy efficiency in small-batch melting. Their design balances toughness, heat transfer, and simplicity of use. Whether you’re crafting great fashion jewelry or running lab examinations, they deliver strong results every time.

5 FAQs of 1Kg 2Kg 3Kg Graphite Crucible Filling Silicon Carbide Graphite Crucible

Frequently Asked Questions

What sizes are available for this graphite crucible?

We offer three standard capacities: 1kg, 2kg, and 3kg. Each size is designed to hold molten metal safely during melting or casting. Choose the size that best fits your typical batch volume.

What material is the crucible made of?

The crucible is made from high-purity graphite filled with silicon carbide. This mix gives it strong heat resistance and better durability than regular graphite alone. It handles repeated heating and cooling without cracking easily.

Can it be used in induction furnaces?

Yes. This crucible works well in both gas-fired and electric induction furnaces. Its conductive properties allow efficient heating in induction setups. Make sure your furnace matches the crucible’s size and power rating.

How long does the crucible last?

Lifespan depends on how often you use it and your operating conditions. With proper handling—like slow preheating and avoiding thermal shock—it can last many melting cycles. Do not drop it or expose it to sudden temperature changes.

Is special handling required before first use?

Yes. Always preheat the crucible slowly before adding metal. Start at low heat and raise the temperature gradually over 30–60 minutes. This removes moisture and prevents cracks. Never place cold metal into a hot crucible—it may cause breakage.
