The formation of TaC and Ta2C by combustion synthesis from their elemental constituents has been studied by time-resolved x-ray diffraction (TRXRD) using synchrotron radiation. The reactions have been followed with a time resolution down to 50 ms. Si

Many solid-state chemical reactions are accompanied by the evolution of heat (I). The amount of heat evolved varies over a wide range (e.g. 300 to 1200 cal gI) and is determined by the chemical system. In conventional methods used to synthesize inorg

An experimental machine for repotting hardy ornamental nursery stock (HONS) from 0·5 to 31 containers has been developed and is described. The transplanting mechanism is based on helical wire devices which are wound into the rootball. Eight of these

The process of combustion synthesis was used to produce ceramic-metal composite materials consisting of titanium carbide (TiC) and an intermetallic alloy of the Ni-Al system. The samples were produced by rapidly heating a mixture of elemental Ti, C,

The combustion synthesis of the common ferroelectric material, BaTiO3, was developed using the stoichiometry: BaO2+0.2 Ti+0.8 TiO2→BaTiO3+0.3 O2. An adiabatic temperature, Tad, of the reaction was calculated from known thermodynamic data to be 1917

Real-time synchrotron diffraction has been used to monitor the phase transformations of highly exothermic, fast self-propagating solid combustion reactions on a subsecond time scale down to 100 milliseconds and in some instances to 10 milliseconds. T
