We take rigorous quality control measures throughout the manufacturing process to ensure they meet or exceed specific standards. This includes dimensional checks, surface roughness, visual inspection and testing for purity, mechanical strength, and other critical properties.
The magnesium oxide crucible will be securely packed in a wooden case, cushioned with soft materials, to prevent any movement within the case.
In certain semiconductor manufacturing processes, MgO crucibles are used for high-temperature treatments, such as annealing or sintering, during the production of semiconductor devices.
Magnesium oxide crucibles are specifically designed for protecting ceramic products like β-Al2O3 from corrosion and volatility at high temperatures.
MgO crucibles are essential in producing dielectric materials like ceramics and thin films, and also crucial in the production of components for sensors, actuators, and transducers. Additionally, MgO crucibles are used to create pyroelectric materials that generate electric charges in response to temperature changes.
MgO crucibles stand as indispensable tools in ensuring the reliability and integrity of the final nickel-based super alloy products, facilitating the creation of high-performance alloys with superior mechanical and thermal properties.
The ability to withstand high temperatures, resist chemical reactions, and provide a controlled processing environment makes MgO crucibles essential for ensuring the integrity, purity, and safety of plutonium and uranium related material processing operations.
MgO crucibles has a high melting point of approximately 2,800°C, making it suitable for use in applications involving extreme temperatures.
MgO crucibles exhibit excellent chemical inertness, resisting attack from most acids, alkalis, and molten metals, ideal for handling corrosive materials in various industrial processes.
MgO crucibles have relatively lower thermal conductivity than graphite or silicon carbide, advantageous in processes where controlled heating or thermal insulation is desired.
MgO is an electrical insulator, making MgO crucibles suitable for applications involving high-temperature electrical resistance heating or where electrical insulation is required.
MgO surfaces usually display non-wetting properties, preventing molten metals and other substances from sticking to the crucible walls.
MgO crucibles are compatible with oxidizing atmospheres, suitable for applications where controlled oxidation is desired or where exposure to oxygen is unavoidable.
When purchasing magnesium oxide crucibles, several important considerations should be taken into account to ensure that the selected crucibles meet the specific needs of your application. Here are some key considerations:
The purity level is important for your choice of purchasing magnesium oxide crucibles, ensuring that the crucibles meet industry standards and are manufactured using high-quality materials to guarantee consistent performance.
Consider the compatibility of MgO crucibles with the materials you will be processing. While MgO is chemically inert in many cases, compatibility with specific chemicals and materials should be verified to prevent reactions that could affect your process.
Specify the required size and shape of the crucibles based on the volume and dimensions of your materials.
Check if the manufacturer offers customization options, such as special coatings or modifications, to meet specific requirements unique to your application.
Confirm the lead time for the production and delivery of the MgO crucibles. Ensure that the supplier can meet your timeline requirements, especially if your project has time-sensitive aspects.
Alumina Crucible
MgO Crucible
MgO crucibles have a better chemical resistance than that of alumina. MgO crucibles are usually inert to metals, slags, and superconductor compounds. In the synthesis or sintering of lithium solid-state electrolyte, MgO crucibles have the distinct advantage of not reacting with lithium, unlike alumina crucibles. Besides, alumina can react with alkaline substances.
MgO crucibles, with a higher melting point of 2800℃ compared to alumina crucibles at 2020℃, are ideal for ultrahigh-temperature processes up to 2200°C.
Alumina crucibles, with a Mohs hardness of 9, are harder than MgO crucibles, which have a hardness ranging from 5.5 to 6.5.
