Perhaps the most impactful invention in modern history, the transistor is at the core of semiconductor devices and has dramatically transformed virtually every industry while helping spawn many new ones. As illustrated in Figure 1, today’s microchips can contain over a billion transistors and are improving our cars, phones, and refrigerators—empowering internet searches, genetic research, and smart sensors. How different would our world be today without these integrated circuit (IC) “microchips?”
Zirconia is a versatile material with interesting physical and chemical properties. When stabilized with yttria, it is useful across a range of industries, especially for physically demanding structural ceramic applications that require high strength and wear, as well as fracture resistance.
Additive manufacturing (AM) of ceramics doesn’t seem to garner the same attention as AM for plastics and metals. Our industry is smaller, and our products are more often behind the scenes in applications. Ceramic processing is also more complicated in many ways than that for plastics and metals.
From next-generation missile domes for defense systems to hip implant components for the medical industry, the mechanical properties of ceramic materials make them ideal for a wide range of applications.
Within the defense industry, advanced ceramics are at the heart of modern armor systems due to their comparatively low weight and high performance during ballistic-scale impacts. Ceramic materials have been developed as an armor material since World War I, when enameling of steel plates was shown to improve their resistance to incoming bullets.
The addition of ultra-thin alumina virtually eliminates the barrier to electricity flow within the battery, allowing for efficient charging and discharging of the stored energy.
