the kroll process is a pyrometallurgical industrial process used to produce metallic titanium.it was invented in 1940 by william j. kroll in luxembourg.after moving to the united states kroll further developed the method for the production of zirconium.the kroll process replaced the hunter process for almost all commercial production.
what is the kroll process titanium is a remarkable metal. it is durable and strong yet light and flexible. it is corrosive resistant and biocompatible. its unique properties has made titanium widely used among many industries from defense to medicine.
