insulating Si3N4 ceramic tube oil cup mug
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Due to different preparation processes, various types of Silicon Nitride Ceramics have different microstructures (such as porosity and pore morphology, grain morphology, intergranular morphology, and intercrystalline second phase content). In order to obtain Si3N4 ceramic materials with excellent performance, high-quality Si3N4 powder should be prepared first. The quality of Si3N4 powder prepared by different methods is not exactly the same, which leads to the difference in its application. The failure of many ceramic materials is often attributed to Developers do not understand the difference between various ceramic powders, and have insufficient understanding of their properties. Generally speaking, high-quality Si3N4 powder should have high α phase content, uniform composition, less impurities and uniform distribution in ceramics, and small particle size. The α phase of the Si3N4 powder with good particle size distribution and good dispersion is at least 90%. This is because during the sintering process, some α phase will change into β phase, but there is not enough α phase content. Will reduce the strength of ceramic materials. At present, China's large and medium-sized ceramic abrasives production backbone enterprises, mainly in the use of hierarchical furnaces, or is gradually upgrading the level of the furnace, these enterprises include the original The state-owned large and medium-sized backbone enterprises, the reformed joint-stock enterprises, foreign-funded enterprises and joint ventures, and some private enterprises developed this year, the number of enterprises is mainly located in coastal areas, Jiangsu, Zhejiang and domestic large and medium-sized cities. In the 1000-3000 tons or more, its product varieties have certain characteristics, can produce high-end products, and some products have reached the level of similar foreign high-quality products. These enterprises are the mainstream enterprises of China's ceramic abrasives production, and many other small and medium-sized enterprises. The third level of kiln, some of which have or are gradually being transformed into the second level of kiln, which uses a small ejector direct-fired drawer kiln, many of these enterprises are distributed throughout the country.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
