General ceramic materials will have burrs on the surface when they are sintered. In order to meet the requirements of use, the surface is often brighter and smoother by polishing. Next, Pintejin Ceramics will introduce the polishing of mirror zirconia ceramics. After the zirconia ceramic parts are formed and sintered, there will be many uneven peaks and valleys on the surface, so it is necessary to grind and polish a super-finishing method that has a significant effect on ceramic roughness. From the perspective of material removal mechanism, grinding is a machining method between brittle failure and elastic removal of zirconia ceramic structural parts, while polishing is basically carried out within Read more

Most ceramic products are basically white, and the color of alumina ceramics is of course the same. But for what reason, these ceramic products will turn from white castings to light yellow after a long time of use. Is it because the color of the alumina ceramics has changed? Of course not, the Pintejin Ceramics Factory will give you a detailed introduction. !Alumina ceramic rod The reason why the color of alumina ceramics is white and gradually becomes light yellow is because the internal composition changes after sunlight exposure, and this change is irreversible, so the color will also change. On the other hand, it may be that the alumina Read more

Structural ceramic materials are divided into two categories: structural materials and functional materials. When a material mainly uses its mechanical properties, this material is called a structural material. If it mainly uses its non-mechanical properties, it is called a functional material. In the literature, functional materials are often defined as “materials that utilize their physical properties”. From the perspective of discipline classification, physical properties are relative to chemical properties, mechanical properties are included in physical properties, and functional materials include chemical functional materials. Appropriately, mechanical properties usually refer to strength, plasticity, toughness, elasticity, hardness, fatigue, etc.; non-mechanical properties mainly refer to sound, electricity, time, magnetism, and chemistry. Structural Ceramics For Read more

Zirconia ceramic laser machining uses a uniform laser beam with high energy density (108-1O10W/cm2) as a heat source to generate instantaneous high temperature at a local point on the surface of the processed ceramic material, and local point melting or gasification to remove the material. Laser machining is a non-contact and frictionless machining technology. No mold is required in the machining process. By controlling the focusing position of the laser beam on the surface of the ceramic material, the machining of three-dimensional complex shape materials is realized. Ceramic laser machining is suitable for micro-drilling, micro-cutting, and micro-structure fabrication on inorganic materials such as organics and ceramics. At present, micro-holes with Read more

Zirconia ceramics have excellent properties such as high melting point and boiling point, high hardness, good toughness, good wear resistance, insulators at room temperature, and electrical conductivity at high temperatures. What are the machining processes of zirconia ceramics? Next, Pintejin Ceramics to introduce to you. Zirconia ceramic machining flow 1. Purchase of raw materials, namely zirconia powder, zirconia powder is a white heavy amorphous powder, odorless, tasteless, soluble in a mixture of 2 parts of sulfuric acid and 1 part of water, slightly soluble in hydrochloric acid and nitric acid, slow Soluble in hydrofluoric acid, almost insoluble in water.It is irritating, the relative density is 5.85. The melting point is Read more
