\r\n<\/strong>Magnesium Oxide Crucible<\/p>\r\n

Introduction to Magnesium Oxide Crucibles:<\/strong>
\r\nThe primary material of magnesium oxide ceramic crucibles is MgO (magnesium oxide). Yttrium oxide can be added as a stabilizer to enhance chemical stability, depending on specific requirements.
\r\nThese crucibles are mainly used for alloy melting in induction furnaces.<\/p>\r\n<\/div>\r\n

\r\nMinimum Volume: 0.0057 ml
\r\nMaximum Size: H400mm x OD300mm x ID280mm
\r\nMaximum Volume: 3644.25 ml<\/p>\r\n

Advantages of Magnesium Oxide Crucibles:<\/strong>
\r\nThe maximum operating temperature can reach up to 2200\u00b0C under specific conditions. (Note: Excessive temperatures during alloy melting may cause oxygen and aluminum contamination in the melt.)
\r\nApplications of Magnesium Oxide Crucibles:
\r\nOxide refractory materials for induction melting crucibles mainly include MgO and Al\u2082O\u2083. In certain applications, MgO crucibles can replace Al\u2082O\u2083 crucibles.
\r\nBy controlling refining temperature and time, high-quality high-temperature alloy ingots can be produced.
\r\nMelting tire cord steel
\r\nMelting AerMet100 steel (under 50-100 Pa vacuum)
\r\nMelting plutonium, uranium, and nickel-based alloys<\/p>\r\n

FAQ\uff1a<\/strong>
\r\nQ1. What chemical reactions occur in Magnesia (MgO) crucibles under high vacuum and high-temperature conditions?
\r\nA1. As the vacuum level and refining temperature increase, Magnesia (MgO) crucibles tend to decompose free oxygen, which is then introduced into the molten steel.<\/p>\r\n

Q2. What is the optimal storage environment for magnesium oxide ceramics?
\r\nA2. Magnesia (MgO) ceramics are highly susceptible to moisture and hydrolysis; therefore, they require a dry storage environment.<\/p>\r\n

Q3. How can thermal cracking in magnesia (MgO) crucibles be prevented?
\r\nA3. Magnesia (MgO) crucibles are sensitive to thermal shock and require uniform heating. It is recommended to increase the temperature by no more than 200\u00b0C per hour.<\/p>\r\n
