HPQ NC1 LA12 INFORMATION

This is both a very high purity Silica and finely divided it is used as a filler where UV transmission and lack of alpha emitting elements is important. High Purity Quartz is completely different from standard commercial grades; the buyer can expect substantially different results due to the near zero impurities.
