Calcium disilicide

DSC analysis revealed two consecutive exothermic reactions with onset at both 472 and 512°C. The combined heat release is equal to 130J g, which is about half the energy released in the stoichiometric CaSi2/PTFE pyrolant. [Pg.113]

Hahma developed high-density pyrolants for autophagous nose cones for advanced infrared decoy flares with improved kinematic separation behaviour [46]. Typical payloads are depicted [Pg.113]

In steelmaking applications, calcium disilicide has hitherto been generally more widely used than calcium metal. Total consumption of calcium disilicide in the steel industry worldwide is estimated to be about 6000 tons (30% Ca). Principal producers are Pechiney Electrometallurgie of France and SKW Trostberg of Germany. In the United States, the Norwegian company Elkem Metal produces up to 2500 metric tons of calcium disilicide. Also produced are CalSiBar, a calcium—silicon—barium alloy, and Hypercal, a calcium—silicon—barium—aluminum ferroalloy. [Pg.401]

Investigations in this field have mainly used calcium silicides. In the Ca/Si system there are two silicides with Si-Si bonds in polymeric systems. In calcium monosilicide the silicon atoms are arranged in form of chains, while the calcium disilicide CaSi2 has a layer lattice, consisting of silicon- and calcium layers. It is possible to form polymeric compounds (SiX) and (SiX2) from both silicides by replacing calcium. [Pg.107]

The wet oxide reacts explosively with molten aluminum-magnesium aUoys. Violent reaction when heated with powdered aluminum, calcium disilicide, magnesium, metal acetyKdes (e.g., calcium acetyKde + iron(III) chloride (on ignition), cesium acetyKde (incandescent reaction when warmed), rubidium acetyKde). Reacts violently with Al, Ca(OCl)2, N2H4, ethylene oxide. See also IRON and IRON COMPOUNDS. [Pg.778]

Calcium disilicide reacts with acids to form the Wohler siloxene [1] or Kautsky siloxene [2], depending on the reaction conditions. These compounds show interesting optical behavior [3]. In the Kautsky formula, silicon six-membered rings are connected by oxygen atoms forming a polymeric layer (Fig. 1). [Pg.327]
