 · Different types of diodes have different voltage requirements. For silicon diodes the forward voltage is 0.7v and for germanium it is 0.3v. In silicon diode, the dark band indicates the cathode terminal and the other terminal is anode. Generally diodes are used as reverse polarity protector and transient protector.

The combination of W and SiC has many applications such as a hot cell of a thermionic energy converter, nuclear material, and high temperature microelectronics. In this study, a 2 µm thick TiN film is introduced as a diffusion barrier between SiC and W to avoid the inter‐diffusion reaction at high temperature.

Advanced Powder Technology IX | p.2

Abstract: TiFe compound was produced by high-energy ball milling of TiH 2 and Fe powders, followed by heating under vacuum. TiH 2 was used instead of Ti in order to avoid the strong particles adhesion to grinding balls and vial walls. Mixtures of TiH 2 and Fe powders were dry-milled in a planetary mill for times ranging from 5 to 40 hours. The amount of sample, number and diameter of the balls ...
