Etching Method for Zirconium Metals and Determination of Dissolved Zirconium Content in Hydrofluoric Acid-Nitrate Aqueous Etching Beds

摘要

A PROCESS TO DETERMINE THE CONTENT OF ZIRCONIUM DISSOLVED IN A BATHROOM (7) TO RECORD THE STRONG WATER OF NITRIC ACID - FLUORIZED ACID FOR ZIRCONIUM ITEMS DETERMINING THE TEMPERATURE INCREASE OF A BATHROOM VOLUME (7) DURING THE DURATION OF KNOWN ZIRCON METAL (15) DIPPING A KNOWN AMOUNT OF ZIRCON METAL (15) IN ONE PORTION OF THE BATHROOM (7), MEASURING THE TEMPERATURE INCREASE IN A DEFAULT PERIOD OF SUCH PORTION (7), DETERMINING THE CONTENT OF DISSOLVED ZIRCONIA OF THE BATHROOM (7) AS A FUNCTION OF INCREASING TEMPERATURE AND TREATING THE BATHROOM (7) DEPENDING ON THE CONTENT OF DISSOLVED ZIRCONIA TO BE DETERMINED IN THE BATHROOM (7).
