Tenders are invited for 2017000407 Calcium Silicide
The Cambridge research will explore the pros and cons of different fuel combinations, including thorium, plutonium and the main material the designers are focusing on, uranium silicide
, which is more power dense and so more cost-effective than the uranium oxide currently used.
The story follows the return to Dolvia's savannah of Brianna Miller as she struggles to protect the tribes during a conflict with the Borabean who seek to capture the new mineral silicide
These power packs, which contain sodium silicide
, don't degrade over time, and when you add water (even sea water), they produce the hydrogen needed for the conversion to electricity.
The system offers not only processing for silicide
applications, but also handles other applications such as MEMS with Ni and Co films, so further expansion of the market can be expected in the future.
The source of these cartridges is called sodium silicide
According to the company, sodium silicide
is a safe, air-stable reactive metal powder that produces hydrogen at about half the pressure of a soda can.
The driving force for silicon diffusion out is believed to originate from the negative Gibbs free energy of Nb silicide
The substance--a manganese silicide
named Brownleeite--appears to have come from comet 26P/Grigg-Skjellerup, NASA announced June 12.
and boride ceramics can be used to high temperatures as well but are more sensitive to variations in film purity and require poisonous gases to form from base metals.
Tantalum nitride, tantalum silicide
and ruthenium oxide are common resistor materials, although the materials may be changed to suit the resistivity and power handling requirements, temperature coefficient of resistance (TCR), and processing capabilities.
Lockheed subcontracted for two types of silicide
fiber products, (1) a pre-impregnated material made from Nicalon Silicon carbide fibers, and (2) silicide
fiber made from Tyranno fibers.
