Why does alumina ceramics change color

Why does alumina ceramics change color Alumina ceramic is actually a ceramic structural component formed by adding alumina during ceramic production, so it will appear white. However, if the raw material contains impurities, the alumina ceramic will turn yellow or gray. However, the vast majority of alumina ceramic products are basically white, and alumina ceramic is also in a white state similar to alumina ceramic. After a long period of use, our ceramic products will change from white castings to [...]

Why Alumina Ceramic Bulletproof Sheet Is Popular

Why Alumina Ceramic Bulletproof Sheet Is Popular As an important component of the bulletproof field, ceramic bulletproof has many special advantages that metals do not have. Ceramic bulletproof materials rely on their high specific stiffness, high specific strength, and chemical inertness in many environments. Its advantage over metal lies in that metal materials produce plastic deformation and absorb energy when resisting bullet impact, while ceramics hardly produce plastic deformation, and rely on their strong and high hardness characteristics to passivate [...]

The quietly rising diamond wire loop saw

The quietly rising diamond wire loop saw Diamond wire loop saw is a cutting tool that solidifies diamond abrasive particles onto a circular steel wire substrate. The saw wire is circular. When in use, it is generally wound onto several guide wheels for unidirectional circular cutting. During the cutting process, there is no need to reverse direction. The cutting speed is high, the cutting seam is narrow, and the surface of the slice is flat. It can cut large sized [...]
