Hebei Messi Biology Co., Ltd. stated that microwave dielectric ceramics refer to ceramic materials that are used in the microwave frequency band (300mhz~300ghz) as a medium to complete the corresponding functions. The moderate dielectric constant, low dielectric loss and good stability in the microwave frequency band make microwave dielectric ceramics widely used in wireless communication devices such as resonators, filters, and dielectric antennas. Magnesium oxide has excellent dielectric properties. The sintering of magnesium oxide and fluoride can effectively improve the microwave dielectric properties of the final microwave dielectric ceramics.
High-purity nano magnesium oxide (MgO) is added to microwave dielectric ceramics to improve their electrical properties. Magnesium oxide has a high dielectric constant, so it can store electrical energy more efficiently than other materials. When magnesium oxide is added to ceramic materials, it increases the overall dielectric constant of the material, thereby improving its ability to store and transmit electrical energy.
It is worth noting that the amount of magnesium oxide added will also affect the performance of microwave dielectric ceramics. Within a certain range, the dielectric constant gradually increases with the increase of magnesium oxide content, but when the magnesium oxide content exceeds a certain range, the dielectric constant gradually decreases. In addition to improving electrical properties, magnesium oxide also helps control the sintering process. Sintering is the process of heating a ceramic material to a high temperature and then cooling it into a solid. Magnesium oxide controls the sintering process by reducing the sintering temperature of the ceramic material. It reduces the energy required for the sintering process, making it more energy-efficient.
In addition, magnesium oxide can improve the strength and durability of the finished ceramic object by helping to control the grain size of the material during the sintering process. In summary, adding appropriate magnesium oxide to microwave dielectric ceramics can improve their electrical properties and control the sintering process, resulting in more energy-efficient and durable ceramic products.
