Purge ZR

Purge ZR (Zirconia Furnace Decontaminator) is a double-activated ion and oxide-absorbing material that eliminates...See more contaminates that can cause discoloration and porcelain delamination in zirconia copings. For example, the low levels of radioactive materials found in zirconium can build up inside a muffle and cause color problems; with Purge ZR, these radioactive isotopes are absorbed completely out of the furnace. Purge ZR should be used once a week in zirconia alumina or firing furnaces to extend muffle/thermocouple life and maintain thermocouple accuracy. From VISION USA, a Dentrex Co., the Purge ZR kit with Ceramic Crucible contains enough material for 25 cleanings.
