Ti-C pyrolant

It is shown that 3 -increases with increasing and that the maximum I is obtained at xi(0-80). Since a Ti-C pyrolant is a heterogeneous mixture, the reaction rate is highly dependent on xi. as well as on the particle sizes of both Ti and C. [Pg.321]

The ignition temperature of a mixture of Ti and C is relatively high compared with those of other pyrolants. When a small amount of polytetrafluoroethylene (Tf) is added to a Ti-C pyrolant, the ignition temperature is significantly lowered due to the exothermic reaction between Ti and Tf Since Tf consists of a -C2F4- chemical structure, the oxidizer gas, F2, is formed by thermal decomposition of Tf according to ... [Pg.321]

These processes are accompanied by heat release, similar to the reaction of Tf and Mg, i. e.. Mg particles are oxidized to form MgF2- It has been reported that the exothermic reaction between Ti and C occurs only when the mixture is heated above 2000 K. Since the reaction between Ti and Tf occurs at a lower temperature of about 830 K, the remaining Ti within the Ti-C pyrolant readily reacts with C with the aid of the heat generated by this reaction. [Pg.321]

The reaction between Ti and Nj occurs in the low-temperature region at below Ti(0-2) for Ti-GAP pyrolants. On the other hand, the reaction between Ti and C occurs in the high-temperature region at above Ti(0-2). The reactions of Ti with N2 and C are represented by ... [Pg.319]

Pyrolants composed of titanium (Ti) and carbon (C) react to form titanium carbide (TiC) according to ... [Pg.320]

Since the reaction of Ti occurs at the surface of each particle, the reaction of the Ti and C particles is dependent on the total surface area of the Ti particles, 3xi, incorporated into the pyrolant. The relationship between the burning rate, r, and Pxi... [Pg.321]
