There was once a flying dream hidden in the myths and legends of the ancients, and people never gave up on the flying dream. With the continuous progress of technology, from the launch of satellites to manned aviation, the human dream of flying has been completed step by step. Now, those aerospace technology is more advanced, the aircraft performance is better. So what role does the zirconia ceramic substrate play in it?
A rocket is launched until it breaks through the atmosphere and then launches a satellite or vehicle into space. This process is driven by a rocket engine, and then the temperature before the turbine of the first stage engine is more than 1500 ° C, and the current maximum temperature of superalloys and metallides is less than 1200 ° C, so the zirconia ceramic substrate can meet the requirements. In the peripheral detection sensor will also be affected, although the temperature will be reduced, but there will be several hundred degrees, the general material of the circuit board will not be directly damaged, there will be performance loss, greatly affecting the sensor work. However, zirconia ceramic substrate has high heat resistance and will not be affected by the spread.
When breaking through the atmosphere, there will be a large external friction, which affects various internal sensors, and temperature, pressure and other sensors are most affected. There is not only a lot of force coming from the outside, but also a lot of heat. In the pressure sensor, its accuracy is very important, if the internal circuit board is damaged by external force, then the pressure sensor means that it is disabled. If the zirconia ceramic substrate is in it, with its high wear resistance and compression resistance, there is basically no damage.
At the same time, there are all kinds of radiation in space. These are deadly to organic materials, causing chemical properties to mutate. However, the ceramic material is inorganic material, which has good performance in radiation resistance and corrosion resistance. And the various sensors on the aircraft are also exposed to space, and the circuit system inside will also be penetrated, so the use of zirconia ceramics as a circuit board can extend its life. In space, it is in a low temperature state, generally tens of degrees below zero, which is basically not used for heat dissipation. Therefore, zirconia ceramic circuit board is the best choice.
I believe that with its joining, in the aerospace field, the aircraft will be able to fly higher and live longer in space!
