Single crystal IC silicon is often remelted and cast for use in solar applications; frequently a mix of high res and low res material. Is there a simple calculation method to produce the resistivity of hi and low res Si mixed in a melt, given the high-to-low res ratio and average resistivity reading for both high and low resistivity starting silicon? For example 100kg of .002 ohm cm start silicon with 500kg 18 ohm cm silicon (assuming both are single crystal - high purity, IC grade start silicon) ---- Thank you very much --- your website is fantastic and rich in interesting information. - Rick
