Zeolite mineral electron microprobe analysis of sodium count rate of change over time

HO L occupied by the pore diameter is 0.26nm, so the Na I (radius 0.098nm) in their migration rates are relatively low in = for the mordenite and clinoptilolite, second ring diameter of the main channel of the L option 0 .70 nm, because no large radius ion play a supportive role, easy to fold trap blocked pores, so that L Drive into 0.4nm, wells were H: 0 occupied. Na occupies only six-membered ring constituted by the pore size of 0.28nm in the channel, is not conducive to Na migration. When the pore size of Taiwan proper channels, such as Na and Ca components Stilbite six-ring channels occupied, L diameter of 0.27 ~ 0. ? Nm, there are a large number of large radius of Ca (radius 0.104nm) play a supportive role, will be conducive to a small amount of small radius in which the rapid migration of Na,[link widoczny dla zalogowanych], coupled with the presence of zeolite water greatly improved the migration rate of ions, resulting in the migration of Na rate greater than the melting together of vaporization rate = In addition, the factors that affect the ion migration rate of crystallization of minerals also the direction of the grain boundary and the experimental conditions, usually along the channel direction more conducive to ion mobility, grain boundary will reduce the tim of energy, so more than the single crystal grain, grain edge, the emblem of ignorance edge crack within the more beneficial than the ion mobility. 3 ways to improve the accuracy of quantitative analysis to reduce water loss and ion dissociation,[link widoczny dla zalogowanych], baking melting, vaporization is to improve the accuracy of quantitative analysis of zeolite minerals should be noted that the main problem = usually be the following specific methods: (I) cooling test with liquid ammonia Sample F (2) a lower abundance of a current probe, due to increase in diameter and accelerating voltage electron beam to reduce the measurement time: (3) analysis of micro-mobility samples continuously, or with stone block area scanning method; (4) Apply a thin sample surface water layer. According to our experience, using the method (2), (3) or (2), (3), (4) end the practice of units easier. The satisfactory conclusion can be explained not only zeolite mineral electron microprobe analysis of sodium in the mechanism of instability, can also be used to explain and predict potential instability of sodium,[link widoczny dla zalogowanych], potassium,[link widoczny dla zalogowanych], calcium and other mineral type material t pull and research for searching fast ion conductor is also of significance References 1 King, Poon slot, Weng Ling Po.

For the general preparation of complex-type material of paper is to hope (about 0.Imm thick cellulose acetate film, that is, AC paper) cover the workpiece drops of acetone or onto the surface of the sample produced. because they use a made acetate film base film, it can use waste acetate film base negatives to produce metallurgical complex type. Specific methods are as follows: (1) waste film (surface layer of silver having Yunnan removed) cut into strips dissolved in acetone, made of resin solution. recipe {waste film 1g + acetone 20mL. melting time of about one day. (2) seep tube drawing drops of melted colloid samples of the third hour etched grinding surface, then the sample with a slightly larger than the optical film of the negative paste waste covered in it. Thus, the excess solution is squeezed out, the remaining colloid addition to filling the gap structure of grinding metallographic sample In addition,[link widoczny dla zalogowanych], the contact part of the softening of the film in turn, remove the branding for the system to be dry good replica. Note: (1) lit waste film, such as burn quickly, you can determine the film for the acetate film base (2) Production Complex Type Specimen some of the erosion of time should be slightly longer. (3) observe the complex type should be a level of pressure on the sample, the complex-type flat = (4) after re-type photographic film, to enhance contrast t should be used for developing hard developer = for example: direct use of Kodak D-? 6R replacement fluid. or in Kodak D-72 developer for 10% of Yunnan in the potassium solution of 10mL; phase should be used for printing paper 4.
