Ceramic Materials

High-temperature ceramic materials are essential in modern industries where extreme conditions are common, such as aerospace, energy production, electronics, and advanced manufacturing. These materials exhibit exceptional properties like high thermal resistance, mechanical strength, and durability under harsh conditions.

Boron Nitride is an advanced ceramic material synthesized from hexagonal boron nitride and is often referred to as "white graphite" due to its white appearance. Boron nitride exists in various structural forms and manufacturing processes, resulting in different types of boron nitride materials, such as hot-pressed boron nitride and pyrolytic boron nitride, each with distinct properties and applications.

Among the various forms of AlN ceramics, mirror-polished AlN ceramic plates stand out due to their remarkable surface smoothness, enhanced flatness, and precise dimensional tolerances. These attributes significantly improve the material’s functional performance, making it a preferred choice for applications that demand high precision, reliability, and aesthetic quality.

Macor ceramic, fully known as "Machinable Ceramic," is a type of machinable glass ceramic. This unique engineering material is widely used in aerospace, semiconductor, laboratory equipment, and other high-tech fields due to its excellent machinability, thermal stability, and electrical insulation properties.

Common colors of zirconia ceramics include white, black, pink, and blue. These colors correspond to different chemical compositions and crystal structures, leading to variations in their properties.

Since Garvie et al. published "Ceramic Steel" in the journal Nature in 1975, research on phase transformation ceramic toughening related to zirconia has been receiving significant attention. One of the most classic examples is the introduction of zirconia into alumina ceramics, resulting in Zirconia Toughened Alumina (ZTA) ceramics.

Zirconia ceramic blades are manufactured using high-purity ultra-fine zirconia as raw material, through processes such as spray granulation, isostatic pressing, and precision machining. They feature high hardness, strong corrosion resistance, good chemical stability, and high wear resistance.

Ceramic substrates are commonly used materials for electronic packaging. Currently, several commonly used electronic ceramic substrate materials include alumina (Al2O3), aluminum nitride (AlN), and silicon nitride (Si3N4). Due to the excellent properties of electronic ceramic substrates, they find extensive applications in fields such as electronics, optoelectronics, telecommunications, aerospace, among others.

In terms of applications, whether in rockets soaring into space or cars racing on highways, or in indestructible cutting tools and robust artificial bones, silicon nitride ceramics have become an indispensable key material in industrial technology, particularly in advanced technology fields. It represents one of the major directions in the development of modern materials science.

Hexagonal boron nitride (h-BN) is a crystalline structure composed of nitrogen and boron atoms arranged in a hexagonal lattice. It is the only phase of boron nitride that exists naturally in the environment. It appears as a soft, loose, smooth, and moisture-absorbing white powder, and it shares similar layered structure characteristics with graphene, earning it the nickname "white graphite."
