矿渣微晶玻璃的研制

粉煤灰是燃煤过程中产生的一种粉状固体废物。目前,我国粉煤灰年排放量达1．5亿t,冲灰用水量达到10多亿m^3,贮灰场占地达250万hm^2。煤矸石是目前排放量最大的工业废弃物之一,占煤炭产量的10％～15％。目前,我国共有煤矸石山1500多座,煤矸石积存总量约50亿t,占地160万hm^2以上,而且每年约以2．0亿t的速度递增,煤炭行业每年投入煤矸石处置费15亿元左右。随着能源需求量的增加,煤炭固体废物的产生量也与日俱增,对于我们这个水资源缺乏,可耕地人均占有率很低的国家来说,如何做好粉煤灰和煤矸石的利用和处置确实是一个十分重要的问题。因此,它们的有效利用是节能、保护环境的有效途径,是可持续发展的必由之路。

Preparation of diffusion coatings in ion-electron melts

A procedure of Ni, Cr, Mn, Co, and Mo (Me) transfer onto iron substrate in ionic-electronic melts LiCl-Li, CaCl2-Ca, and BaCl2-Ba was elaborated and the transport processes were studied. The saturated vapor pressure of these ionic-electronic melts is as low as enabled working at atmosphere pressure in an inert media up to 1000 ℃.Armco iron was used as a substrate because it practically does not interact with lithium, calcium, and barium. The metals-diffusants were put into the melts in the form of a powder. The complete saturation of the melts with lithium, calcium, and barium was ensured by a preceding contact of a molten salt with an excess of Li, Ca, or Ba before loading of iron.The reactions take place despite the metals and iron were separated from each other by the molten salt. The quantity of the metals transfered was determined by the change in mass before and after experiments, by microprobe analysis, and x-raying of the iron surface layer. The experiments were carried out at 900, 950 and 1000℃ during 5, 10, 15 and 20 hours.At the first stage of the process the formation of the ionic-electronic melt occurs. For example, dissolution of calcium in the case of the system CaCl2-Ca is mainly proceeded in the form of one-valent cations: Ca + Ca2+()Ca+. As soon as the metal-diffusance is immersed into the melt, its dissolution in the form of negative ions takes place: Me + Ca+() Me-+ Ca2+. In the vicinity of the iron substrate the last equilibrium will shift to the left generating a solid solution or intermetallide. The thickness of the diffusion layer rises as the temperature and saturation time increase. The obtained coverings were 20-60 (m thick,and their surface layer contained 15,-80, (mass fraction) of the metal-diffusance.Both the composition of the melt and the procedure of the coverings preparation in ionic-electronic melts have been patented (Patent RU2058422, 1996, pr. 30.09.93).
