High-temperature dielectric thermospectroscopy measurement system in vacuum and atmosphere_Evaluating dielectric material properties

Bailibo high-temperature dielectric measurement system with vacuum and atmosphere
Independently designed, the first multi-functional electric heating furnace in China
The multi-functional electric heating furnace can measure the dielectric of samples under conditions such as broadband, high-temperature, vacuum atmosphere, etc. Performance, vacuum and atmosphere are of great significance to the protection of the specimen being measured and the measuring fixture system. The multifunctional heating furnace adopts a double-layer structure made of stainless steel. The inner layer is used to install the fiber furnace, and the outer layer is mainly used for vacuuming and insulation. This design structure can achieve measurement conditions such as vacuuming and filling the inner tank. The fiber furnace has the highest It can be achieved, the furnace insulation effect is good and the performance is stable. The multifunctional heating furnace can measure the dielectric properties of materials under vacuum and different atmosphere conditions. This function is currently the first domestic measurement platform for dielectric property measurement.
Self-weighted electrode fixture system, the first choice for piezoelectric ceramics
Based on the principle of parallel plate capacitors, the electrode system designed by our company uses the arm's self-weighted type to fix the sample. Traditionally, the spring type is used to fix the sample. The size of the spring force is directly related to To determine the adhesion of the conductive silver paste on the sample to be tested, we have proven through experiments that fixing the sample using its own weight will greatly improve the phenomenon of the conductive silver paste on the sample sticking to the electrode. Another important benefit of using the self-weight method to fix the sample is that the measurement of piezoelectric ceramics is more accurate.
The principle of parallel plate capacitor is usually used to measure dielectric properties. It is ideal to use two parallel plates for the upper and lower electrodes. However, in fact, during the sample production and measurement process, it is impossible for the sample to be in complete contact with the upper and lower electrode plates. , usually one or several points are in contact with the sample to be measured. If the conductivity of a certain contact point is not good, it will easily lead to unstable sample measurement.
In order to avoid the above phenomenon, our company's upper electrode is made of platinum and is integrally processed into a hemispherical shape, while the lower electrode is still a flat plate. This electrode system can accurately position and measure a certain point of the sample being measured, thereby making the system repeatable and stable. Sex is better.
Simulating wire shielding under high temperature conditions can effectively increase the frequency bandwidth of the test and reduce the AC interference of the electric furnace wire
In order to solve the problem that the wire is interfered by the AC signal of the electric furnace wire under high temperature, a high-temperature dielectric measurement system was established High-temperature wire shielding model, this model effectively reduces the interference of external signals and increases the test frequency bandwidth. Usually we use the wire test method from the impedance analyzer to the measurement electrode. It is required that the wire connected to the electrode should be as unshielded as possible and the distance should be as short as possible. , the commonly used shielding layer materials cannot be used in high temperature environments, so we cover the platinum leads with ceramic insulating materials, use stainless steel tubes as shields for the leads, and then use stainless steel metal blocks to connect the shields of the upper and lower electrodes to form a shielding layer loop to achieve resistance to AC interference.
