Silicon Nitride Ceramic:

Industrial ceramics, that is, ceramics for industrial production and industrial products are mainly acid and alkali resistant, high wear resistance, ordinary ceramics are not wear-resistant and not resistant to acid and alkali, ordinary ceramics such as our daily ceramics, and sanitary ware, these are common ceramics,. The density and porosity of the material were measured by the Archimedes method, the three-point bending method and the Vickers hardness test method by adding the sintering aid and using the atmospheric pressure sintering process to prepare Silicon Nitride Ceramics with different porosity (19%~54%). Bending strength and hardness The phase composition and microstructure were examined by X-ray diffraction and scanning electron microscopy. The dielectric properties of silicon nitride ceramics at 10.2 GHz were tested by cavity method. Silicon nitride ceramic beads can reach HRC 80 degrees. , the extreme high temperature is about 800 degrees
It is extremely resistant to high temperatures and its strength can be maintained to a high temperature of 1200 ° C without falling. It does not melt into a melt after being heated, and will not decompose until 1900 ° C.
At 1285 degrees, it reacts with dicalcium dinitrate to form calcium sulphide sulphide. At 600 degrees, the transition metal is reduced, nitrogen oxides are released, and the flexural strength is 147 MPa.
The key to this method is to use a simple bond test to create an axisymmetric (or coin-like) crack at the coating substrate interface of a conventional tensile specimen. The tensile stress at both ends is shown in Figure 2. A critical peel force can be measured, so that the critical nominal normal stress can be obtained. The method needs to use the finite element program to numerically analyze the crack buried in the interface. It is considered that the coating model is flawless and the crack is artificially made on the interface. Subject to far field uniaxial tension
Some special ceramic materials also have a glass phase. Because of the liquid phase formation during the firing process, it can reduce the sintering temperature, prevent polycrystalline transformation, inhibit grain growth and promote grain adhesion.
