Diatomite
Diatomite or diatomaceous earth is a sediment greatly enriched in biogenic silica in the form of siliceous skeleta of diatoms, a diverse array of microscopic, single-cell algae. These frustules are sufficiently durable to retain much of their structure through long periods of geologic time and through thermal processing. Diatomite products have an inherently intricate and highly porous structure composed primarily of silica.
Flux Calcination
Calcination in the presence of a fluxing agent. In general, the presence of a flux during calcination reduces the temperature at which sintering and agglomeration of diatomite particles occurs, thus permitting larger agglomerates to form and extending the permeability range of filter aids. A common fluxing agent is sodium carbonate (Na2CO3).

What is scientific name of diatoms?
Diatoms are algae, diatoms are protists. Diatoms are placed in the division Bacilliariophyta, which is distinguished by the presence of an inorganic cell wall composed of hydrated silica.
What Do Diatoms look like?
Diatoms are usually microscopic, but they can be 2mm in length. Marine diatoms are a yellowish brown colour.
What is meaning of flux density?
Like the number of sunspots, the Flux Density Values reflect the Sun's magnetic activity, which affects the rate at which the Sun radiates energy and warmth.
