POTASSIUM PYROANTIMONATE
Potassium Pyro Antimonate is an antimony compound having Sb+5, making it useful as a crosslinker for gums. Besides various other uses, PPA is also used in hydroseeding, water gels and oil well stimulants.
Potassium pyroantimonate is a chemical compound of antimony. Antimony is a metallic element with the chemical symbol Sb and atomic number 51. Small amounts of antimony are found in the earth's crust.
The use of 2% potassium pyroanti- monate added to fixatives appears to serve as a method to detect cell swelling and to indicate which cells are most susceptible to swelling. After leaching the kidney blocks in sodium-free phosphate buffer, no precipitate was found.
