This inorganic, water-dispersed, alumina-filled ceramic adhesive is made to bond and seal thermocouple probes in high-temperature environments up to 3,200F (1,760C). It can be put on with a brush, spatula or syringe, and cures in one to two hours at 700F. It gets stronger the hotter it gets, with tensile-shear strength of 900 psi through curing at 1,000F. It's an inert, chemically-resistant adhesive that won't outgas in ultra high vacuum, and, as an electrical insulator, has a resistivity of 109 Ù-cm and a dielectric strength of 250 V/mil. It can also be used in the assembly of dense ceramic components used in ultra-high vacuum equipment, repairing of ceramic saggar plates, and bonding and coating of platinum/rhodium resistance wires to aluminum oxide heaters and other applications.
Sciaky, provider of electron-beam additive manufacturing (EBAM) services, will start selling these machines commercially in September. The company has used its EBAM 3D printing technology for making very large, high-value, metal prototypes and production parts for aerospace and defense OEMs.
At this year’s Google I/O, the spotlight was pointed on gender inequality in the high-tech industry. Google has established a new initiative that it hopes will even out the playing field, Made w/Code. Part of this initiative will fund free online courses in basic coding.
