Aremco's new single-part, ceramic-filled adhesive paste can bond to ceramic, metal, and quartz, and has a dielectric strength of 200 volts per mil, volume resistivity of 109 ohm-cm, coefficient of thermal expansion of 4.2in/in/ F, and a torque strength of 6.0 ft-lbs. It is rated up to 3,000 F (1,650C). It goes on with a brush, syringe, or automatic dispenser. It cures in 24 hours at room temperature, or can cure in two hours at 200F. When cured, it resists moisture and thermal shock. Made for assembly of igniters, thermocouples, probes and sensors such as oxygen analyzers, gas chromatographs, mass spectrometers, and high-vacuum components, it comes from stock in pint, quart, gallon and five-gallon pails.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
