2002-3-11 The green–yellow glass granules were then transferred into a glove box for further processing. The uranium glass was found to be more brittle than the matrix glass and a revised and simpler processing route by ball milling only, without jet milling, was adopted. No separation of the size fractions after ball milling was carried out.

Since this mini-review mainly focuses on the conditions applied for the preparation
2008-12-19 Therefore in this study the effects of ball-milling on the glass transition of wheat flour constituents were investigated. RESULTS: Crude gluten, non-gluten proteins and separated starch were obtained from wheat flour ball-milled for 0–10 h, and the glass transition temperature ( T g ) of these constituents was evaluated.
2016-5-6 Wet milling in a ball mill is used to prepare a suspension based on amorphous and crystallized magnesium aluminum silicate glass. The stabilizing additives used are hydrochloric and oxalic acids, and also an aqueous ammonia solution. Raw material is molded by slip casting in porous molds. Optimum ranges are provided for magnesium aluminum silicate glass suspension casting parameters in order
High-purity borosilicate glass was prepared by blending of powders, melting and grinding by ball milling and jet milling to a powder of about 12 μm. A quantity of this glass was then blended with U 3 O 8,melted and milled to powder.
2014-9-5 However, this is low efficient and high cost. Glass powders suitable for preparing paste need to be very fine, usually 10 µm and a narrow size distribution. It is difficult for hard materials like glass to be downsized to such small size by ball milling. In this paper, a
2019-12-12 Then the glass liquid is poured into the pre-prepared deionized water for slow and uniform quenching. Finally, the glass frit was washed 2–3 times with deionized water and ethanol after ball milling to remove impurities and was vacuum dried for 6 h at 60 ℃ to complete the preparation of the 2% Ag-doped glass

Abstract The (100 − x)Na3BO3·xNa2SO4 (0 ≤ x (mol%) ≤ 50) glasses were prepared by mechanical milling. Halo patterns were observed in the compositions 0 ≤ x ≤ 50 by XRD measurements. The Raman spectra indicated that all the glasses were composed of BO33− anions, SO42− anions and Na+ cations. The (100 − x)Na3BO3·xNa2SO4 glasses showed good deformation properties and a dense
