Properties. Calcium silie is a white freeflowing powder. It can be derived from naturally occurring limestone and diatomaceous earth, a siliceous sedimentary rock. [citation needed] It is one of a group of compounds that can be produced by reacting calcium oxide and silica in various ratios 3CaO·SiO 2, Ca 3 SiO 5; 2CaO·SiO 2, Ca 2 SiO 4; 3CaO·2SiO 2, Ca 3 Si 2 O 7 and CaO·SiO 2 ...

Asbestos has been used intermittently in small amounts for thousands of years. Modern industrial use dates from about 1880, when the Quebec chrysotile fields began to be exploited. During the next 50 years gradual increases in production and use were reported with a cumulative total of somewhat less than 5000 million kg mined by 1930 .

· The aim of this work was to establish whether asbestos fibers homogeneously occur in the different fractions ground from naturally occurring asbestos lithotypes, and to calculate the contribution of fibers from each fraction to the overall concentration in the sample. Serpentinite, metabasalt, calcschist, clay, debris material, and soil, were addressed. Grain size fractions below 20 mm were ...

There is increasing evidence that fibre size and shape play an important part in the production of health effects related to asbestos. The dimensions of airborne fibres collected at various stages of fibre processing in three mines and six mills producing three types of asbestos were measured using phase contrast light microscopy and transmission electron microscopy.
