杭州九朋新材料

essential information:

CAS number: 1309-48-4

Molecular formula: MgO

Relative molecular weight: 40.3

Melting point: 2800 ℃

Technical indicators:

characteristic:

1. High chemical purity, MgO ≥ 99.0%; 2. Good suspension performance in water, convenient for coating

3. It has a certain degree of adhesion.

Application:

1. Prepare magnesium oxide foam ceramic filter, which is used for purifying alloy liquid, and solves the technical problem that the existing technical filter does not pass through magnesium alloy and high-temperature alloy containing active elements,

2. Prepare magnesium oxide ceramic cores, which shall be used at a temperature not lower than 1600 ℃ and shall not react with the casting metal under high temperature conditions. The casting surface shall be smooth and the surface roughness shall not exceed 10 μ m; It compensates for the defects such as a large number of pores and sand sticking caused by the use of silicon-based cores in casting such materials; Excellent solubility, able to dissolve well in weak acids, short core removal time, simple core removal equipment, pollution-free and safe core removal process, reducing precision casting costs; Pouring hollow thin-walled castings without thermal cracking; High precision in core size; Having sufficient strength, it does not deform or break during shaping, handling, and furnace loading.

3. Prepare molten ceramic particles together with alumina, which can be widely used in the field of grinding tools.

4. Using rare earth oxides as sintering aids, silicon nitride ceramics can be prepared efficiently and economically to manufacture various complex shaped products, such as cutting tools, sealing rings, bearings, nozzles, and various high-temperature, wear-resistant, and corrosion-resistant products.

5. Prepare high toughness ceramic materials, and use high-purity magnesium oxide and yttrium oxide or rare earth metal oxides as composite stabilizers to sinter and heat treat partially stabilized zirconia ceramics with excellent mechanical properties and resistance to high-temperature aging. This ceramic material can be widely used as high-temperature engineering components and advanced refractory materials.
