Particle Size Distribution

1994
The objectives of this test are: 1. Measure the distribution of sizes of particles in a ceramic raw material from its largest size DL ≈ 6700 lim (6.7 mm) to its smallest size D, ≈ 0.010 \μm. Unfortunately there is no single apparatus which is capable of measuring this range of sizes, common in the classical ceramic industry. Consequently, it may

The distribution of particle sizes

Journal of the Franklin Institute, 1950
Abstract In this paper the older literature on distribution of particle sizes is reviewed critically. The distribution law should be connected with the law of growth of crystals, for which is chosen the exponential law as Galton indicated long ago in an analogous case. The law which then follows is the so-called Logarithmico-Normal law.

Technegas and Pertechnegas particle size distribution

European Journal of Nuclear Medicine, 1995
Technegas and Pertechnegas are radioactive aerosols produced in a commercial generator and used for lung scintigraphy. The aerosols are produced by first evaporating to dryness standard technetium-99m generator eluate (99mTcO4 in normal saline) in a graphite crucible (the simmer stage) and then heating this to 2500 degrees C (the "burn" stage). The aim

Particle Size Distribution of Settled Dust

Journal of the Air Pollution Control Association, 1965
In 1958, San Bernardino County Air Pollution Control District adopted rules and regulations for the control of dust, fumes and particulate matter. These were taken from ordinances which had been effectively used in other areas. After three years, experience showed that in some instances these rules and regulations should be modified to take into ...

Particle Size and Distribution

2018
Particle size distribution, the measure of subdivision of a solid, can be directly correlated with uniformity of quality and performance. Primary particle size is a physicochemical property that may impact temporal chemical and physical effects such as stability and aggregation.

Particle Size Distribution

2017
In this chapter, a state of the art of Particle Size Distribution (PSD) measurement of bio-based aggregates and characterization methods is presented. Shiv particles coming from the stem of plants cultivated either for their fibers (hemp, flax, etc.) or for their seeds (oleaginous flax, sunflower, etc.) are very different from the mineral aggregates ...

Estimating Functionals of Particle Size Distributions

Biometrika, 1971
SUMMARY Data consisting of the intersections of a planar or linear probe with a field of spheres, with a diameter distribution G(x), is often used to estimate linear functionals or their ratios. It is shown that distribution-free estimators may be poor and that their distribution, even in large samples, depends on knowledge of G for small x that may be

PARTICLE‐SIZE DISTRIBUTION OF GLAZES*

Journal of the American Ceramic Society, 1941
A bstract The particle‐size distributions of experimental and commercial stains and glazes and glaze materials were determined by using the Andreasen pipette method. The variation in particle size of two porcelain glazes, raw and fritted, was correlated with the glaze working

A study of particle size distributions

Powder Technology, 1990
Abstract The properties of a size distribution of particulate materials are systematically discussed. In order to avoid possible conceptual problems and difficulty in dealing with a distribution, some boundary conditions are given, based on which the limitations of the distribution functions in the literature are discussed.

Estimation of linear properties of particle size distributions

Biometrika, 1970
This paper presents a general mathematical theory for quantitative investigation of the properties of a dilutely distributed particulate phase. If the process by which the specimen is sampled and the process by which particles in the sample are measured can be appropriately modelled, then this theory provides unbiased estimates of any linear property ...
