    • An object of the present invention is to provide more inexpensive high purity crystalline silicon which can satisfy not only a quality required to a raw material of silicon for a solar cell but also a part of a quality required to silicon for an up-to-date semiconductor and a production process for the same and provide high purity silicon tetrachloride used for production of high purity crystalline silicon and a production process for the same. The high purity crystalline silicon of the present invention has a boron content of 0.015 ppmw or less and a zinc content of 50 to 1000 ppbw. The production process for high purity crystalline silicon according to the present invention is characterized by that a silicon tetrachloride gas and a zinc gas are supplied to a vertical reactor to react them at 800 to 1200°C, whereby crude crystalline silicon is formed at a chip part of a silicon tetrachloride gas-supplying nozzle, and the crude crystalline silicon is grown downward from the chip part of the silicon tetrachloride gas-supplying nozzle; the grown crude crystalline silicon is discharged to an outside of the reactor, and the discharged crude crystalline silicon is subjected to acid treatment.
