High Flow GaCl3 Delivery
First Claim
1. An apparatus for deliverying high purity gallium trichloride in the vapor phase to a reactor for producing gallium-containing products, comprising;
- a source of an inert carrier gas at a pressure elevated above atmospheric pressure;
a heater capable of heating the carrier gas to a temperature of at least 80°
C.;
a container having a corrosive resistant inner surface having a supply of gallium trichloride, a valve controlled inlet for the carrier gas that forms a dip tube with an outlet below the level of the gallium trichloride, a valve controlled outlet for removing the carrier gas and gallium trichloride entrained in the carrier gas;
a heater capable of heating the container sufficient to melt the gallium trichloride;
a delivery line connected to the valve controlled outlet for carrying the carrier gas and entrained gallium trichloride to a reaction zone for converting the gallium trichloride to gallium-containing products.

Abstract
The present invention is an apparatus for deliverying high purity gallium trichloride in the vapor phase to a gallium nitride reactor, comprising; a source of carrier gas at an elevated pressure; a purifier to remove moisture from the carrier gas; a heater capable of heating the carrier gas to at least 80° C.; a container having a supply of gallium trichloride, a valve controlled inlet for the carrier gas having a dip tube with an outlet below the level of the gallium trichloride, a valve controlled outlet for removing the carrier gas and entrained gallium trichloride; a heater capable of heating sufficient to melt the gallium trichloride; a delivery line connected to the valve controlled outlet for carrying the entrained gallium trichloride to a reaction zone for gallium nitride. A process is also described for the apparatus.
