[求助]
求一個SiO2-Al2O3-P2O5體系的三角形玻璃形成區(qū)域相圖 已有1人參與
|
|
求助木蟲上的各位大神： 現(xiàn)在老板讓設(shè)計一個SiO2-Al2O3-P2O5體系的玻璃配方，于是開始找這個體系的玻璃生成相圖， 怎么也找不到，結(jié)合其他相圖只能推出兩個點。。求大神幫忙找找，文獻(xiàn)中的也行，高手推導(dǎo)出的也行，金幣奉上！ |

Al2O3-SiO2-P2O5 Fig. 93-156—System P2O5-SiO2-Al2O3. Solid state phase relationships in air from 900¡ã-1100¡ãC. Mul = Al6Si2O13; Trd = tridymite (SiO2). R. Umlauf, H. Von Platen, A. A. Forughi, and P. Bartha, Ber. Dtsch. Keram. Ges., 57 [4-5] 83-85 (1980). An unspecified number of compositions were prepared, using unspecified raw materials. Samples were annealed at 300¡ã, 600¡ã, 700¡ã, 900¡ã, and 1100¡ãC for periods up to 25 d. Loss of P2O5 was avoided through the use of double-crimped Au-Pt tubes to contain all mixtures. Phase identification was performed using Guinier X-ray diffraction, with CuKa radiation and Si as internal standard. The ternary compound was found to be formed reproducibly at all temperatures above 700¡ãC, with some indication of phase formation below that temperature. The chemical formula Si2AlP3O13 was determined using an energy-dispersive microprobe system (average of 45 measurements on 4 specimens). The compound exists in two stable crystallographic modifications; a third modification is obtained irreproducibly on grinding the crystal. Both stable modifications exhibit hexagonal prismatic growth habit and have negative optical extinction. Indexed X-ray data for the stable modifications are given, determined from single-crystal precession X-ray diffraction (MoKa radiation) from selected fragments of both crystal types. The high-temperature phase is said to be trigonal, space group P321, P3m1, or P3¡￥m1, with a = 3.212 nm and c = 0.886 nm, but powder data can be indexed using a hexagonal pseudocell with a = 0.803 nm and c = 0.886 nm. The stable, low-temperature phase is hexagonal, space group P6322, with a = 0.801 nm and c = 0.920 nm. Figure 364 shows a compound, Si2P2O9, but Ref. 1 confirms the composition as Si5P6O25. The principal ternary phase assemblages indicated are as determined by Forughi.2 Tie-lines in two-phase regions have been added for clarity by the editors. 1. A. E. Mal'shikov, Zh. Neorg. Khim., 32 [10] 2370-2374 (1987); Russ. J. Inorg. Chem. (Engl. Transl.), 32 [10] 1383-1385 (1987). 2. A. A. Forughi; "Phase Relations in Al2O3-P2O5 and SiO2-Al2O3-P2O5 Systems"; Ph.D. Dissertation.
