A system and method for mechanically supporting and electrically coupling arc tubes in high intensity discharge (“HID”) lamps such as metal halide lamps. The system and method provides mechanical support and electrical coupling of the arc tube in HID lamps with few or no welds and is particularly suited for HID lamps having relatively large arc tubes, e.g. lamps having wattages greater than about 150 watts or other wattage lamps having a heat reflector mounted near the base of the lamp.

A processing system and associated method for milling boron with impurity contamination avoidance. The system includes a jet mill for reducing the particle size of a boron feed stock, and a feed stock inlet for delivering the boron feed stock toward the jet mill. The system includes at least one inlet for delivering at least one gas into the jet mill. The gas and the boron feed stock comingle within the jet mill during milling reduction of boron particle size. The system includes a source of the at least one gas operatively connected to the at least one inlet, with the at least one gas being a gas that avoids transferring impurity during milling reduction of boron particle size.

Methods for removing an organic contaminant from contaminated boron powder include providing a contaminated boron powder, the boron powder being comingled with an organic contaminant. The method also includes placing the contaminated boron powder onto an inert container and placing the inert container and the contaminated boron powder into an enclosed space. The enclosed space environment is altered to create an oxygen deficient atmosphere. A heat source is provided to heat the contaminated boron powder to an elevated temperature. The method includes vaporizing the organic contaminant so as to reduce the amount of the organic contaminant comingled with the boron powder. Another method includes reducing the amount of the organic contaminant comingled with the boron powder to not more than about 0.1 weight percent of soluble residue.
