Abstract:
1. Apparatus for producing material by a chemical reaction between a first chemical reagent and a second chemical reagent, comprising: a chemical mixing arrangement having a mixing chamber and injection means configured to produce a jet of a first chemical reagent and a jet of a second chemical reagent such that said jets collide within said mixing chamber to produce a reacting mixture; a dispensing chamber having an inlet for receiving said reacting mixture from said mixing chamber and an outlet for dispensing said reacting mixture; a dispensing piston configured to dispense said reacting mixture from said dispensing chamber; control means for controlling the movement of said dispensing piston and for controlling operation of the chemical mixing arrangement such that said movement of said dispensing piston is co-ordinated with said operation of said chemical mixing arrangement, wherein said control means is configured to cause said chemical mixing arrangement to mix said chemical reagents while simultaneously said dispensing piston is caused to move at a controlled rate.
