Structural ceramics have been growing in popularity due to the need for stronger, lighter, more durable, and resistant materials for various applications. Ceramic material manufacturers continue to innovate and explore new processes to produce the next generation of ceramics. This article will focus on zirconium tungstate, a new type of structural ceramic material that has gained attention in the industry.
Zirconia, alumina (Al2O3), silicon carbide (SiC), aluminum nitride (AlN), and silicon nitride (Si3N4) are some of the commonly used ceramic materials for structural parts. Aluminum-zirconium oxide complexes (ATZ-toughened zirconia) and zirconia-toughened alumina (ZTA) are also gaining popularity. These materials have excellent mechanical properties and are widely used.
Zirconium tungstate is a peculiar material that exhibits the physical phenomenon of thermal shrinkage and cold expansion, which is opposite to the physical phenomena of most materials. This material is called near-zero negative thermal expansion material. Its negative thermal expansion characteristics are maintained within the temperature range of 0.3~1050K, and its performance is isotropic.
Zirconium tungstate has a high negative expansion coefficient, making it an ideal material for low-expansion performance. It is often used in combination with zirconia or alumina in a certain ratio to maintain the integration of carrying capacity and structural functions of materials. Due to its low thermal expansion coefficient, ZrO2/ZrW2O8 ceramic matrix composites have wide application prospects in precision instrument manufacturing, optics, aerospace, electronics, and other fields. Zirconium tungstate also performs well in stability, mechanical properties, fracture toughness, and conductive thermal conductivity at high temperatures and in cold environments.
Zirconium tungstate is a new type of structural ceramic material that has gained attention due to its unique properties and applications. While it may be slightly expensive, it has the potential to lead to a large-scale upgrade in aerospace equipment, laser equipment, optical communication systems, and microelectronics. Advanced Ceramic Materials is one of the reliable suppliers of high-quality zirconia ceramics and related products for research and production needs.
