Possible Directions in Recycling Crystal Production Waste

Methods are proposed for regeneration and subsequent recycling of waste generated in lead crystal production, such as diamond cutting and chemical polishing slime and acid sewage neutralization waste. The specified methods provide for additional economic effects and substantial environmental improvement and make it possible to produce new types of materials (a complex lead-bearing material, low-melting glasses, foam materials).__________Translated from Steklo i Keramika, No. 1, pp. 12 – 14, January, 2005.     

Construction materials based on cullet

The results of the development of decorative, heat-insulating and soundproof construction materials based on glass cullet are discussed. The service parameters of the samples are determined and the optimum technological production schemes are developed. Translated from Steklo i Keramika, No. 1, pp. 4–6, January, 1999.

Estimation of siltation of the Tereblya-Rika hydroelectric station reservoir

Conclusions An estimation of the suspended-load discharge with the use of the existing data of hydrological yearbooks was not very reliable, since it gave quite underestimated results of the calculation in comparison with the actual volumes of siltation of the reservoir.The bed-load discharge calculated on the basis of data on the migration of meso-forms and a detailed analysis of the actual maximum runoff hydrographs of the Tereblya River, characterized by the transport of channel-forming sediments, is in good agreement with the data of the particle-size analysis of the reservoir siltation products and amounts to not more than 1% of the total sediment load.On the basis of a statistical analysis of the data of field observations, a lognormal relation was established between the volumes of water and sediment discharges, reflecting in a most generalizing form the main characteristics of fluvial processes of streams in the investigated region.With consideration of the substantial changes in the morphometric characteristics of the reservoir, it is economically advisable to change to the use of refined depth curves.Translated from Gidrotekhnicheskoe Stroitel'stvo, No. 7, pp. 47–50, July, 1988.

Effect of the redox potential of the glass batch and cullet on the tinting of industrially produced glass containing iron oxides

The effect of the redox potential of the glass batch and cullet on the tint of industrially produced glasses containing up to 0.5% iron oxides is studied. The batch redox boundaries making it possible to obtain glass of green, bluish-green, yellow-green, and brown tints are delineated. The obtained results make it possible to predict the tint and tint shade of glass at the stage of batch preparation. Translated from Steklo i Keramika, No. 3, pp. 11–12, March, 2000.     

Effectiveness of Alloying Steel with Vanadium from Cored Wire

An analysis is made of the distribution and assimilation of vanadium in finished steel. It is shown that the character of assimilation of vanadium is unstable when lump ferrovanadium is used. Given the same consumption of ferrovanadium per heat, the scatter of vanadium content is 0.007–0.18% (abs.) or 20.6–37.5% (rel.). The alloying of steel by cored wire filled with a vanadium-aluminum master alloy (72.9% V and 26.5% Al) results in a consistently high level of vanadium assimilation – 98.7%. The minimum level of assimilation in this case is 90.1%.     

Effect of Radiation on Glasses in Borosilicate and Boron-Lead-Silicate Systems

The effect of an electron flux and gamma radiation on glasses produced in a synthetic glass batch is considered. The origin of the radiation color centers arising in glasses and the disintegration of these centers in thermal and photodecolorization is investigated.
