Product Overview

0e7fa61b-27b1-4ef0-b451-39bfb997bb64
Graphite is essential high-temperature refractory materials, used in various industrial processes, particularly in metal melting/smelting, lithium battery negative materials firing, and other high-temperature applications.

Made from high-purity graphite or graphite combined, these crucible/pot offer excellent properties such as high thermal conductivity, heat resistance, and chemical stability. The high thermal conductivity ensures efficient melting of materials, while their ability to withstand extreme temperatures (up to 2000°C or more) without degradation makes them ideal for intense industrial environments. Graphite crucible/pot series also feature excellent resistance to chemical corrosion, ensuring that molten metals do not interact with or contaminate the crucible.

Graphite crucible/pot series are more durable compared to other choices, providing significant cost savings over time. The primary applications of graphite crucible/pot series include melting/smelting precious metals like gold, platinum; melting non-ferrous metals such as aluminium, copper and zinc; melting transition metals and facilitating processes in the production of lithium batteries and other high-temperature industrial tasks.

High-Temperature Resistance & Thermal Stability

Graphite can handle extreme temperatures, making it ideal for melting and casting metals at high temperatures without degradation.

Excellent Thermal Conductivity

Graphite's superior ability to conduct heat ensures even and efficient melting of materials, reducing energy consumption and process time.

Chemical Corrosion & Oxidation Resistance

Graphite crucibles do not react with most molten metals and chemicals, ensuring purity of the material being melted.

Longer Service Life

Compared to other materials, graphite crucibles have a much longer service life due to their inherent strength, durability, and resistance to wear and tear.

Sustainability & Graphite Crucibles

L.T Graphite has always paid great attention to the issue of sustainable development, committed to reducing pollution in the production process, and using craftsmanship to create more high-quality graphite products, including a series of crucibles for melting/smelting in the foundry industry.

Environmental Impact of Graphite Production

Measures are taken to control pollution during the graphitization and machining processes, including reducing dust and wastewater emissions during graphite refining, ensuring a cleaner production environment.

Contribution to Carbon Neutrality Goals

As part of global efforts to combat climate change, graphite materials contribute to cleaner energy solutions, particularly in the fields of lithium-ion batteries, hydrogen fuel cells, and renewable energy sources like solar and wind power.

Applications in Renewable Energy

Graphite crucibles are critical in the production of Li-ion batteries and fuel cells, which are used in cleaner transportation solutions and renewable energy systems, helping to reduce carbon emissions and contribute to global carbon neutrality goals.

FAQs on Graphite Crucible Selection and Usage

 If you have any questions or need assistance, please don't hesitate to contact our customer service team.

We are committed to providing you with the highest quality service and support.


How to select the correct graphite crucible for your application?

Just answer the following questions and give the answer to my team, we will give recommendation

1) which kind of materials to be melted, melting temperature?

2) furnace type, Melting chamber dimnensions? or melting capacity you want?

Different kinds of Graphite crucibles, brief introduction?

1) high purity graphite crucible, for gold,platinum etc. Precious melting and cooling

2) medium particle graphite crucible, for transition metal smelting under gas protection environment or vacuum environment

3) Isotropic SIC graphite crucible, for aluminium, copper, tin melting

4) Aluminium gasification use graphite crucible, for gas evaporation gas coating

Can graphite crucibles be used for all metals?

No, pure graphite or graphite combined crucible, not suitable for steel or iron melting, because during the process, need add strong acid or base as cosolvent, which have great corrosion to graphite materials, will short down the service life obviously. But my team have other suitable recommendation, contact us for more information
