Silicon Nitride Ceramic:
The meaning of vacuum refers to the state of gas below one atmospheric pressure in a given space, which is a physical phenomenon. In "Void", sound cannot be transmitted because there is no medium, but the transmission of electromagnetic waves is not affected by vacuum. In fact, in vacuum technology, the vacuum system refers to the atmosphere. Part of the material in a specific space is discharged to make the pressure less than a standard atmospheric pressure. We generally call this space a vacuum or vacuum state. Vacuum often uses Laser Drilling Electronic Ceramic Substrate Strap Board Pascal or Torr as the unit of pressure. In the natural environment, only outer space can be called the space closest to vacuum.
In 1641, the Italian mathematician Torricelli filled a long tube with mercury, and then slowly turned the mouth of the tube into a basin filled with mercury. The end of the mercury column in the tube was 76 cm high. At this time, the mercury-free zone at the top of the glass tube is in a vacuum state. This experiment is called the "Torri Demolition Experiment", and the glass tube that completed the experiment is the "Torri Demolition Tube Laser Drilling Electronic Ceramic Substrate Strap Board".
When Einstein used the field theory view to study the phenomenon of gravitation, he already realized that there is a problem with the empty vacuum concept. He once proposed the idea that vacuum is a special state of the gravitational field. P.A.M. Dirac was the first to give the vacuum a new physical content. In 1930, Laser Drilling Electronic Ceramic Substrate Strap Board in order to get rid of the dilemma of the negative energy solution of the Dirac equation, Dirac proposed that the vacuum is a sea of electrons full of negative energy states.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
