Crystalline silica is the scientific name for a group of minerals composed of silicon and oxygen. The term crystalline refers to the fact that the oxygen and silicon atoms are arranged in a three dimensional repeating pattern. ... Because oxygen is the most abundant element in the Earth's crust and silicon is the second most abundant, the formation of silica is quite common in nature. … quartz, … is the most common form of silica found in nature. Silica can also be biological in origin, produced by tiny organisms. The most significant of these are diatoms (plants) and radiolarians (animals) ... Thus, silica can be found in more than one state—amorphous as in the remains from a diatom and crystalline as in a quartz crystal … Both are SiO2, but they are quite different physically. 3, record 4, English, - crystalline%20silica

Crystalline silica is a basic component of soil, sand, granite, and many other minerals. Quartz is the most common form of crystalline silica.

Diatomite products that are further processed are called calcined and flux calcined diatomite. Most diatomite products are used in filtering applications. With a large particle size distribution, the smallest of the particles occupy space between larger particles. This reduces the rates of flow through the filter. The purpose of calcining is to reduce the particle size distribution. The use of the term calcined is ingrained in the diatomite industry and markets so it is used frequently, but diatomite is actually sinterized not calcined. Sintering reduces the size distribution by melting the smallest particles together. To produce calcined diatomite the natural product is heated to between 900°C and 1100°C. The high temperatures burn off organic contaminants, and shrink and harden the individual particles. Some of the diatom frustules are sintered into small clusters. The resulting calcined diatomite has a density of about 125 to 150 kg per cubic meter. Flux calcined diatomite is produced using the same methods except a fluxing agent is added before heating. 3, record 11, English, - flux%2Dcalcined%20diatomite

La terre de diatomée, nommée également diatomite, est une silice amorphe qui peut contenir à l'état naturel entre 0, 1 et 4 % de silice cristalline, généralement du quartz. Certains procédés industriels comme la calcination à haute température de la terre de diatomée, avec ou sans l'utilisation concomitante de fondants, transforment la silice d’une forme amorphe en une forme cristalline et plus précisément en cristobalite. La terre de diatomée calcinée sans l'aide de fondants peut ainsi contenir de 20 à 30 % de cristobalite, alors que la diatomite calcinée à l'aide de fondants peut être contaminée jusqu'à 60 %. 1, record 11, French, - diatomite%20calcin%C3%A9e%20%C3%A0%20l%26rsquo%3Baide%20de%20fondants
