Beryllium oxide ceramic (Beryllia Ceramic) is a high-performance ceramic material that is widely used in electronics, optoelectronics and thermal management due to its excellent properties such as high thermal conductivity, high dielectric constant and low dielectric loss.
In order to further improve the electrical conductivity and metallization adhesion strength of beryllium oxide ceramics, it is often necessary to metalize their surfaces. Among them, MoMn metallization is a common surface metallization method.
MoMn metallization refers to a metallization treatment in which molybdenum oxide (MoO3) and manganese oxide (MnO2) are used as the main components of the metallization layer and covered on the surface of beryllium oxide ceramics through a process such as high-temperature sintering. The thickness of the metallization layer is usually between 1-5 μm, and its main function is to improve the electrical conductivity of the beryllium oxide ceramics and enhance the adhesion between them and the metal.
The advantages of MoMn metallization are good uniformity of the metalized layer and strong adhesion with the interface of beryllium oxide ceramics, which can effectively prevent the peeling or stripping of the surface of beryllium oxide ceramics. In addition, the resistivity of the MoMn metallization layer is lower than pure metal and has good corrosion resistance and thermal stability, which can still maintain good electrical conductivity and metal adhesion in some high-temperature, high-pressure and corrosive environments.
After MoMn metallization treatment, beryllium oxide ceramics not only have excellent electrical conductivity and metal adhesion strength but also can effectively protect the surface of beryllium oxide ceramics from corrosion, wear and other undesirable factors, which improves its application performance and reliability in the fields of electronics, optoelectronics, and thermal management.
MoMn metalized beryllium oxide ceramics are a widely used microwave dielectric material with good mechanical properties, thermal stability and electrical properties, and therefore are widely used in microwave circuits, microwave filters, antennas and other microwave devices.
Beryllium oxide ceramics itself is an insulating material with low loss and high dielectric constant, which has excellent microwave dielectric properties.MoMn metallization can improve the electrical conductivity of beryllium oxide ceramics, which in turn reduces the loss of the circuit. In addition, MoMn metallization can also improve the bonding of beryllium oxide ceramics and enhance their mechanical strength, which enables them to withstand higher power density and temperature.
In microwave circuit design, MoMn metalized beryllium oxide ceramics can be used to make microwave inductors, capacitors and microwave filters and other components. With the advantages of small size, stable performance and temperature stability, it is widely used in microwave communication, radar, aerospace and other fields.
