Stability of potassium tripolyphosphate-based electrolyte solutions

Stability of potassium tripolyphosphate-based electrolyte solutions. Prodan, E. A.; Lesnikovich, L. A.; Petrovskaya, L. I.; Erusalimchik, I. G.; Zolotareva, E. A. (Inst. Obshch. Neorg. Khim., Minsk, USSR). Elektrokhimiya, 20(11), 1510-15 (Russian) 1984. CODEN: ELKKAX. ISSN: 0424-8570. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) At 20° and 60°, data were obtained on the stability, nature and rate of chem. transformation of K tripolyphosphate (K5P3O10) [13845-36-8] in solns. of electrolytes contg. salts of Ni, Cu, Zn, Ag and Fe. The catalytic effect of cations on the rupture of the bridging P-O bond, depending on the compn. and structure of the complexes which are formed, owing to the transition of the initial tripolyphosphate electrolyte to a polyligand tripolypyrophosphate electrolyte is not the principal obstacle for the electrochem. use of K5P3O10. Based upon the obtained results, the maintenance is explained of the high utilization characteristics of a Ag electroplating bath, which during prolonged electrolysis at 60° does not require correcting with respect to K5P3O10.

SU 1271821 A1 23 Nov 1986 From: Otkrytiya, Izobret. 1986, (43), 97. (Union of Soviet Socialist Republics) CODEN: URXXAF. CLASS: ICM: C01B025-40. APPLICATION: SU 85-3890851 30 Apr 1985. DOCUMENT TYPE: Patent CA Section: 49 (Industrial Inorganic Chemicals) Granular alkali metal tripolyphosphates are prepd. by agglomeration of the product with wetting and subsequent calcination. In order to increase the product yield and quality, tripolyphosphates of K and Na were used and wetting was done with air having relative humidity 60-100% or with water for 1-60 min at 2-50°. Before calcination, the product is crushed and exposed to air for 10-20 h. In one embodiment, it is exposed to air having a relative humidity of 5-55% at 15-30°. .
