Pintejin Ceramics Factory is a professional manufacturer of precision ceramics machining, which can provide customized precision ceramics machining and production according to drawings. Below, Pintejin Ceramics Factory will introduce the sintering technology of precision ceramics to us. Precision ceramic nozzle The sintering technology of precision ceramics mainly includes the following methods: Atmospheric pressure sintering of precision ceramics, also known as pressureless sintering. It belongs to the process of free sintering of the green body under atmospheric pressure. In the absence of external power, the sintering temperature of the material generally reaches the melting point of the material at 0.5-0.8. Solid-phase sintering at this temperature can induce sufficient atomic diffusion in Read more

Although the zirconia ceramics we are familiar with have excellent performance and high hardness, it will inevitably require very precise machining during machining. Next, the Pintejin ceramics manufacturer will introduce to you the finishing methods and attention of zirconia ceramics. point. Finished zirconia ceramic tube Processing method of precision zirconia ceramic machining: Zirconia ceramic machining methods are commonly divided into two categories: mechanical machining, mold injection machining, etc. Among them, the mechanical machining method is highly efficient, so it is widely used in industry. Applications, especially diamond wheel grinding, lapping and polishing are common. Precautions for machining precision zirconia ceramic parts: Although there are many methods for machining precision zirconia Read more

Alumina ceramics are made by using alumina as the main raw material, adding 6-30% of clay, magnesium oxide, calcium oxide, titanium oxide and other sintering accelerators, and sintering at 1450-1800 ℃ after mixing. The more alumina content, the better the inherent properties of alumina can be exerted, and the better the performance, but it becomes difficult to manufacture as the alumina content increases. The characteristics of alumina porcelain are that it still has good insulating properties at high temperature. Pure alumina porcelain can be used at a temperature of 800 ° C. Its mechanical strength is the highest among all oxide ceramics, and its thermal conductivity is large and thermal Read more

Zirconia ceramics and alumina ceramics are relatively common in the market, and their advantages are particularly prominent. Similar industrial ceramics, silicon nitride ceramics, also have some unique advantages. Next, let’s take a look at silicon nitride ceramics and its application in Use in aerospace and more! Silicon nitride ceramics are used in aerospace and military industry, mechanical engineering, communications, electronics, automobiles, energy, chemical biology and other fields because of their high temperature resistance, corrosion resistance, wear resistance and unique electrical properties. Especially in the field of high temperature structural ceramics, silicon nitride ceramics are new materials with the best comprehensive properties, the most application potential and the hope to replace Read more

The development of the fine ceramics industry in China is on the rise, but it is technically different from foreign countries. However, with the support of the state for fine ceramics and the development of science and technology, my country’s fine ceramics industry will develop better and better. Below is an analysis of this industry by Pintejin Ceramics. Due to its excellent properties, fine ceramics are widely used in the fields of national defense, chemical industry, metallurgy, electronics, machinery, aviation, aerospace and biomedicine, and have become an important key material for the development of these fields. attention, its development also affects the development and progress of other industries to a Read more

In modern industry, there are many different kinds of ceramics, and their properties are very different. In the classification of ceramics, alumina ceramics is one of the ceramic materials with low cost. This material has good high temperature resistance and compression performance, and is very popular and purchased by customers. Zirconia ceramics make up for the insufficient tensile strength of alumina ceramics. Among the several types of raw materials, it is a structural ceramic with good physical properties at room temperature. Many gate valves, such as valve balls, high-pressure gate valves, and butterfly valve plates, are all made of zirconia ceramics. Let’s talk about silicon nitride ceramics, which should be Read more
