Solution growth under nonuniform conditions - ammpnium dihydrogen phosphate and magnesium sulfate heptahydrate

Solution growth under nonuniform conditions - ammpnium dihydrogen phosphate and magnesium sulfate heptahydrate. Narayanan, H.; Youngquist, G. R. (Clarkson Univ.Chemicals with cas numbers 7722-76-1 and 10034-99-8 also play role., Potsdam, NY 13676, USA). AIChE Symp. Ser., 83(253, Fundam. Aspects Cryst. Precip. Processes), 47-53 (English) 1987. CODEN: ACSSCQ. ISSN: 0065-8812. DOCUMENT TYPE: Journal CA Section: 75 (Crystallography and Liquid Crystals) The breakdown of planar growth for NH4(H2PO3) and MgSO4.7H2O single crystals was studied using a submerged jet technique. Effects of temp., jet Reynolds no. and nonuniform supersatn. were interpreted using transport modeling combined with growth theory. .

Effect of an active additive on formation of the contact layer between urea granules and the phosphate coating

Effect of an active additive on formation of the contact layer between urea granules and the phosphate coating. Kravets, G. V.; Pravdin, N. N.; Pozin, M. E. (Leningr. Tekhnol. Inst. 89965-59-3 and 10034-99-8 are cas registry numbers. These chemicals are also mentioned in this article., Leningrad, USSR). Zh. Prikl. Khim. (Leningrad), 57(2), 230-3 (Russian) 1984. CODEN: ZPKHAB. ISSN: 0044-4618. DOCUMENT TYPE: Journal CA Section: 19 (Fertilizers, Soils, and Plant Nutrition) Anal. of strength characteristics of a CaHPO4-CO(NH2)2-MgSO4.7H2O mixt. imitating the compn. of the contact layer between the urea granule and the phosphate coating showed that a mixt. compn. with a molar component ratio of 1:1:0.5 had the highest strength. Thus, capsulating urea in a phosphate coating using the MgSO4.7H2O additive, which is chem. active relative to urea, permits increasing the granule strength to 1.4-1.97 MPa and increases the soln. time 3-4.8-fold. .
