Although there have been a number of studies on the ingestion of asbestos, few studies exist on how the chrysotile asbestos itself is altered by the exposure to the acid stomach environment. This study has found that there are changes in the physical, chemical and surface properties of chrysotile as
surface properties of chrysotile asbestos as a result of exposure to water, strong acids, and simulated gastric juices. It was observed that the charge on the surface (the zeta potential) is changed from positive to negative; the surface becomes silicalike; and the magnesium is lost from the fibers of asbestos upon exposure to water and acid.

2012-1-18 ASBESTOS 135 4. CHEMICAL AND PHYSICAL INFORMATION 4.1 CHEMICAL IDENTITY Asbestos is a generic term for a group of six naturally-occurring, fibrous silicate minerals that have been widely used in commercial products. Asbestos minerals fall into two groups or classes, serpentine asbestos and amphibole asbestos.

Using magnetization and Mossbauer measurements we have measured the magnetic properties of chrysotile asbestos originating from different mining locations. The samples show a paramagnetic and ferromagnetic component. The paramagnetic component is due to high spin Fe substituting Mg and Si in the chrysotile lattice. The ferromagnetic component is due to magnetite attached to the asbestos fibers

2019-12-5 Asbestos cement is usually a mixture of about 10% asbestos and 90% Portland cement. The types of asbestos used may vary, chrysotile is normally always present but crocidolite and amosite (asbestos grunerite) were also added to many products. Some sources of chrysotile asbestos also contain small amounts of tremolite asbestos

2012-2-19 Asbestos is a general name applied to a group of silicate minerals which naturally occur in fibrous form. There are six principal asbestos minerals (Fig. 1) which are divided into two main mineral groups: serpentine and amphibole asbestos.The group of serpentine includes only one fibrous silicate mineral—chrysotile.
