A vapor generator (19, 62) and connected chemical vapor deposition chamber (28) for providing a vapor for operations such as chemical vapor deposition has an atomizer (16, 16A, 38, 50) for forming an aerosol or droplet spray (36, 58, 74, 80) separate from a vaporization chamber (19, 62). The aerosol is passed into a heated vaporization chamber (19, 62) wherein the particles or droplets are flash vaporized and larger droplets are vaporized by direct contact with heated surfaces. The resulting gas/vapor stream is then used for chemical vapor deposition, in a separate chemical vapor deposition chamber (26). The vapor and gas stream is preferably passed through a restricted passageway (22, 44, 68) for mixing before being introduced into the chemical vapor deposition chamber (26).
