Uses and Properties of Silicon Carbide Ceramics

Categories: Industry Information
Comments: No

Silicon carbide ceramics outperform other ceramic spare parts in certain industrial applications. There are many ceramic spare parts in the market, such as alumina ceramic parts, zirconia ceramic parts, silicon carbide ceramic parts. The following is a detailed introduction to the use and characteristics of silicon carbide ceramics by Pintejin ceramic manufacturers. Silicon carbide ceramic ring In air, silicon carbide begins to oxidize at 800°C, but very slowly. The oxidation rate increases rapidly with increasing temperature. Silicon carbide oxidizes 1.6 times faster in oxygen than in air and slows down with time. A typical parabolic profile can be obtained if quantitative oxidation traces occur over time, which reflects the effect Read more

The Sol Of Ceramic Powder

Categories: Technical Information
Comments: No

The sol-gel method is a method of converting a sol with a concentrated metal oxide or hydroxide into a gel, and then drying the gel and then calcining it to obtain an oxide. The sol of ceramic powder will be further elaborated by Pintejin ceramic manufacturer below. The sol of ceramic powder first causes fine particles to be suspended in an aqueous solution (sol), and then drops the sol into a dehydrating solvent to make the particles agglomerate into a colloid (ie gel), and then remove the solvent or allow the solute to precipitate. turns into a gel. The pH value of the solution, the ionic or molecular concentration of Read more

Theory and Technology of Grinding Method of Zirconia Ceramics

Categories: Technical Information
Comments: No

In recent years, many scholars have applied the diamond grinding method to systematically study the theory and process of plastic grinding of brittle materials of zirconia ceramics, brittle-plastic transition, material properties, cutting force and other parameters. Plastic way surface formation mechanism and geometric accuracy of zirconium ceramic parts, including research and development of related machine tool and grinding wheel technology. 1. Machining of zirconia ceramics: The machining of zirconia ceramic materials is not only suitable for semi-sintered body ceramics, but also for fully sintered body zirconia ceramics. The cutting process of semi-sintered zirconia ceramics is to reduce the machining allowance of fully sintered body ceramics as much as possible, thereby Read more

Ceramic Grinding Technology

Categories: Technical Information
Comments: No

Grinding usually refers to the use of micron-scale abrasive particles with a hardness that is farther away from the material to be processed, and the micro-cutting and rolling action generated by the hard grinding disc to achieve the removal of trace materials on the machined surface, so that the shape and size of the workpiece are accurate. Reach the required value, reduce the surface roughness, and reduce the machining method of machining the metamorphic layer. 1. Grinding Mechanism Advanced ceramic materials are hard and brittle materials that are difficult to machine. In the grinding process of such materials, the material to be processed is removed by the rolling action or Read more

High-efficiency and high-precision machining method for zirconia ceramic materials

High-efficiency and high-precision machining method for zirconia ceramic materials 1. ELID superfinishing ELID is the abbreviation of Electrolytic Online Dressing Grinding Method. It applies a grinding wheel composed of metal bond and super-hard micro-diamond (or CBN) abrasive, and at the same time electrolytically sharpens the grinding wheel during the grinding process, so that the grinding wheel is always kept sharp, thus ensuring ultra-precision grinding under high efficiency conditions Therefore, it is an advanced method for mirror grinding of brittle materials (such as ceramics, glass, silicon and iron oxide, etc.). The high material removal rate grinding of zirconia ceramic materials by ELID method can greatly reduce the grinding cost. When reasonable Read more
