Sintering is one of the processes in the production of alumina ceramics. So what changes will occur in alumina ceramics before sintering, during sintering, and after sintering?

(1) The level of technical equipment will be rapidly improved: the development of computer technology and digital control technology has promoted the technological progress and rapid development of the advanced ceramic material industry, such as automatic control of continuous sintering kilns, high-power and large-capacity grinding equipment, and high-performance milling Advanced complete sets of equipment such as granulation equipment and other net pressure forming equipment have beneficially promoted the improvement of the overall level of the industry, and at the same time, the production efficiency and product quality have also been significantly improved.

Alumina hollow spheres and their products are a new type of high-temperature thermal insulation refractory material. It has high strength, good chemical stability, light bulk density, and a large number of closed pores. It is widely used in petroleum, chemical, ceramics, and high-temperature and ultra-high temperature for national defense scientific research. On thermal equipment.

In the entire chain of the industrial ceramic chain, the position of the alumina ceramic rod is relatively special, and it is also called the precision ceramic rod. Because in the actual production process, it has very strong technical strength and high standard requirements, which represents the highest level of progress and development of the industrial ceramic industry. In production practice, alumina ceramic rods have launched high-quality products. Creating first-class products to meet the actual needs of modern production is also a basis for development.

The first is alumina ceramics, because alumina ceramics have good mechanical strength, conductivity and high temperature resistance. However, when cleaning alumina ceramics, you must choose the ultrasonic cleaning method, and alumina ceramics​ actually belong to The most widely used ceramic is mainly because of its superior performance, and its application in the current market is becoming more and more extensive. It can not only effectively meet the daily use, but also meet some special needs.

Under high-temperature conditions, creep deformation represents the most critical structural evolution characteristic of alumina ceramic structural components. Unlike their rigid properties at room temperature, ceramic structural parts undergo slow, continuous plastic deformation over time under sustained loading at high temperatures. Moreover, higher temperatures and greater external stresses lead to an accelerated creep rate and more pronounced deformation magnitude.

Currently, the market demand for high-purity, durable and low-pollution industrial ceramic crucibles keeps rising. The 99.3% alumina ceramic crucible launched by Yunxing Industrial Ceramics has become the top choice for high-temperature industrial operations.

Because alumina ceramic has many distinctive properties, it can be made into many different products. For example, because of its high mechanical strength, it can be used as a mechanical structural part, and with its high resistivity and electrical insulation properties With good advantages, alumina ceramic has become an ideal material for products such as substrates, tube sockets, and circuit casings.

The development of alumina (Al2O3) high-temperature insulation ceramics in the industrial field is satisfied with the application of modern technology in various industries. The most common use in "high-precision ceramic parts" products is undoubtedly high-purity alumina ceramics.

During the equipment installation and commissioning phase, uneven bolt tightening torque applied by operators, collisions occurring during handling and assembly, and uneven stress on component mating surfaces will generate transient overload stress, which directly causes chipping and cracking of ceramic parts.
