Production technology

Technical specifications provide for production of calcium zirconium powder of the following grades: PCrK1, PCrK2, PCrKZM, PCrK1M, PCrK2M. Sequence of operations:

  1. - Sintering with lime or calcium carbonate with the addition of CaCl2 at temperatures above 1100 ° C;
  2. - Sintering with soda at temperatures above 1,000°C or fusion with caustic soda (temperature to be above 500°C);
  3. - Leaching of silicon salts contained in the semi-finished product, after which the residue is decomposed in aqueous solutions of sulphuric or hydrochloric acids;
  4. - Sintering with potassium fluorosilicate, temperature about 1000° C;
  5. - Heating of fluorosilicate sinter with subsequent washing in acidified water, resulting in potassium fluorosilicate converted to water; when the solution cools, most of it (75-90%) is released;
  6. - Evaporation of the residue, with obtaining zirconium powder of the required composition.
