Alumina ceramics is a kind of ceramics with a wide range of uses. Because of its superior performance, it is more and more widely used in modern society. So what are the advantages of alumina ceramic structural parts? Next, Pintejin Ceramics will introduce to you. The density of alumina ceramic structural parts is also higher than that of magnesia ceramics. In this case, we measured the density of alumina ceramics to be 3.5. But for the density of alumina ceramic structural parts, we measured 6. In this way, its texture must be more delicate, and after our grinding process, the smoothness of its white surface is also very high, reaching Read more

Zirconia ceramic products have precision errors or tolerance ranges after ceramic machining, so what is the reason for its appearance? Pintejin Ceramics Factory will give you an analysis. ​Zirconium oxide ceramic grinding is a kind of machining method to eliminate chips on the surface of the workpiece. Therefore, the dimensional change in the process of zirconia ceramic machining should be continuous. In the process of zirconia ceramic grinding, it can always reach a high level. accuracy. The grinding and polishing of zirconia ceramics is often the last process in the machining of a workpiece, and it is also a process that determines the accuracy of the workpiece. There is a Read more

Alumina ceramic is an industrial ceramic with high hardness that can only be processed by diamond grinding. It is made of bauxite and can be processed using injection molding, pressing, isostatic pressing, sliding casting, etc., then Pintejin ceramics Let us introduce the properties and characteristics of alumina ceramics. Properties and Characteristics of Alumina Ceramics Using high-purity sub-μm aluminum oxide ultrafine powder, it is possible to produce aluminum oxide high-precision ceramic raw materials with a tensile strength of 700-1000Mpa and a Weber displacement coefficient of 40. However, the impact toughness of such raw materials is extremely low. Generally only 3 ~ 4MPa.m. Therefore, improving the impact toughness of alumina ceramics has Read more

The principle of extrusion molding: the metal powder can be extruded at a certain temperature (usually in the range of 40-200 °C) after adding a certain amount of organic plasticizer to mix evenly. This method is called “cold extrusion method”. Or “plasticized powder extrusion”. It is generally extruded under normal temperature conditions. The ceramic powder used for extrusion molding must be mixed with water and plasticizer to prepare a billet before it can be used for extrusion molding. Vacuuming during the extrusion process is beneficial to the discharge of air in the blank, so that the green density of the shaped blank can be increased. During the extrusion process of Read more

The temperature difference and time of the high-temperature firing treatment after the alumina ceramic blank is formed have a great influence on the finished product. Therefore, the alumina ceramic ceramics have stricter requirements on the firing temperature in terms of performance and quality. To accurately control the sintering temperature, then we should take corresponding measures. Different alumina ceramics have different sintering temperature requirements, and the sintering temperature is actually related to the content of alumina. Theoretically, the higher the alumina content, the higher the sintering temperature. In fact, this statement is not completely absolute. It is also necessary to observe the composition and proportion of ceramic materials. Generally, when we Read more
