yellow phosphorus
4.The productivity of yellow phosphorus, Industrial phosphoric acid, Food-grade is 8000t, 15,000t and 5000t respectively.
5.This paper introduces the hardware set up and software configuration of TDC 300 DCS as well as its successful application for 80 MW electric furnace in yellow phosphorus unit.
6.Article 31 It is forbidden to discharge or dump into any water body or directly bury deadly toxic soluble slag, tailings, etc. containing such substances as mercury, cadmium, arsenic, chromium, lead, cyanide and yellow phosphorus.
7.The comparison between X-ray fluorescence spectra method and chemical analysis method for phosphate ore in yellow phosphorus and double superphosphate production are made. The results showed that the former method is more rapid and accarate.
8.Gallium recovery technology used to recover gallium from recycle solution in Bayer process, zinc leach residue, coal fly ash and fly ash in the production of yellow phosphorus(treater dust) ,and its recent progress are discussed.
9.The phase composition and microstructural changes during the heating of granulated yellow phosphorus slags with an acidity of AK=0.85 (AK=SiO_2/CaO)were studied by XRD, IRS, DTA, DTG, OM, SEM and EPM.
10.InP nanocrystallite was synthesized with the method of refluxing and annealing of organic solvent at ordinary pressure from metal Na, yellow phosphorus and InCl_(3·)4H_(2O) with appropriate amount of dimethylbenzene as solvent.
