Abstract

Among silica-based materials vitreous silica has a special place. The paper presents the melting process of a quartz particle under conditions of low-temperature plasma. A mathematical model is designed for stages of melting in the experimental plasma-chemical reactor. As calculation data show, quartz particles having the radius of 0.21≤ r{sub p} ≤0.64 mm completely melt at W = 0.65 l/s particle feed rate depending on the Nusselt number, while 0.14≤ r{sub p} ≤0.44 mm particles melt at W = 1.4 l/s. Calculation data showed that 2 mm and 0.4 mm quartz particles completely melted during and 0.1 s respectively. Thus, phase transformations occurred in silicon dioxide play the important part in its heating up to the melting temperature.

EFFECTS OF QUARTZ PARTICLE SIZE AND SUCROSE ADDITION ON MELTING BEHAVIOR OF A MELTER FEED FOR HIGH-LEVEL GLASS

Conference J, MARCIAL; AA, KRUGER; PR, HRMA; ...

The behavior of melter feed (a mixture of nuclear waste and glass-forming additives) during waste-glass processing has a significant impact on the rate of the vitrification process. We studied the effects of silica particle size and sucrose addition on the volumetric expansion (foaming) of a high-alumina feed and the rate of dissolution of silica particles in feed samples heated at 5 C/min up to 1200 C. The initial size of quartz particles in feed ranged from 5 to 195 {micro}m. The fraction of the sucrose added ranged from 0 to 0.20 g per g glass. Extensive foaming occurred only inmore »« less

The Effect of Quartz Particle Size and Melt Viscosity on HLW Melter Feed Using Pellet Test Response - 16226

Conference Lee, SeungMin; Hilliard, Zachary; Heilman-Moor, Jayven; ...

Melter performance is affected by various physical and chemical parameters of the feed. To study the effect of these parameters on waste glass melting efficiency, we monitored the volume expansion of feed pellets in response to heating. This study focuses on the effects of quartz particle size and melt viscosity on a simplified high-alumina high-level waste melter feed labeled A19. In this research the A19 feed was prepared with eight different partitions of quartz particle size ranging from 5 to 250 μm and six modified A19 feeds were formulated to produce melts of viscosities that varied from 1 to 30more »« less
NuSTAR J033202-2746.8: Direct constraints on the Compton reflection in a heavily obscured quasar at z ≈ 2

Journal Article Del Moro, A.; Mullaney, J.; Alexander, D.; ... - Astrophysical Journal

We report Nuclear Spectroscopic Telescope Array (NuSTAR) observations of NuSTAR J033202-2746.8, a heavily obscured, radio-loud quasar detected in the Extended Chandra Deep Field-South, the deepest layer of the NuSTAR extragalactic survey (∼400 ks, at its deepest). NuSTAR J033202-2746.8 is reliably detected by NuSTAR only at E > 8 keV and has a very flat spectral slope in the NuSTAR energy band (Γ=0.55{sub −0.64}{sup +0.62}; 3-30 keV). Combining the NuSTAR data with extremely deep observations by Chandra and XMM-Newton (4 Ms and 3 Ms, respectively), we constrain the broad-band X-ray spectrum of NuSTAR J033202-2746.8, indicating that this source is a heavilymore »« less

Two-level systems in electron-irradiated quartz

Journal Article Laermans, C; Vanelstraete, A - Phys. Rev. B: Condens. Matter; (United States)

The longitudinal ultrasonic attenuation in electron-irradiated crystalline quartz (dose of 1.0 x 10/sup 20/ e/cm/sup 20/, E-italic = 2 MeV) was measured in the temperature range 1.4--300 K, at a frequency of 640 MHz. The data show conclusive evidence for the existence of two-level systems, similar to those in glasses. A relaxation attenuation is observed, giving rise to a T-italic/sup 3/ behavior at the lowest temperatures that levels off to a shoulder at about 10 K. The derived density of states is smaller than that in vitreous silica.
