doi:10.1002/jctb.5010111002The rates of dissolution in dilute sodium hydroxide solution of a series of size‐graded powders of the four common polymorphic forms of silica (quartz, tridymite, cristobalite and vitreous silica) have been studied and found to be in keeping with their physical ...
As part of fundamental studies in silicosis research, the rates of dissolution in 0.1 M-hydrofluoric acid of size-graded powders of quartz, tridymite, cristobalite and vitreous silica, having particle diameters in the range 0.2–5.0 μ, have been measured by a conductimetric micromethod. The rate...
The higher this fraction is in the coal dust, especially if rich in crystalline silica and/or metals, the higher the potential cell inflammation and consequent health damage (Brodny and Tutak, 2018; Castranova, 2000; Cohen et al., 2008; Ercal et al., 2001; Ghio and Madden, 2017; ...
Simple models for silicon fraction of signal vs incident electron voltage suggest this behavour is due to a heterogeneous particle structure in which an aluminosilicate coating occludes the surface of a silica particle core. The coating survives incubation in a major component of pulmonary surfactant....
Silica Measurement with High Flow Rate Respirable Size Selective Samplers: A Field Study. High and low flow rate respirable size selective samplers including the CIP10-R (10 l min(-1)), FSP10 (11.2 l min(-1)), GK2.69 (4.4 l min(-1)), 10-mm nylon... Taekhee,Lee,Martin,... -...
The specifications are based on results obtained in a detailed investigation of the properties of respirable-size α-quartz samples from 12 different geological and commercial sources. The properties investigated were amorphous surface content, crystallinity index, preferred orientation, and particle size ...
and earth-moving activities involved in construction and remediation. Respirable dust particles that can enter the lungs and penetrate further into the gas exchange region are much finer. Respirable dust particles may contain quartz, silica, and various hazardous metals, made airborne via grinding or ...
