What does asbestos look like is a question for many people to know the material containing asbestos. Viewed from the standpoint of chemistry, asbestos is a substance composed of magnesium-calcium-silicate fiber with very strong physical properties.
There are two groups of asbestos, which is serpentine and amphibole. Asbestos can be obtained by various underground mining methods, but the most common is through open pit mining. Utilization of asbestos is containing radiological risk because this material can serve as a source of radioactive radon gas, so it can serve as a source of environmental radiation to watch.
It is now being recognized that indoor radon gas is the most important source of radiation exposure. Effective dose from radon is estimated to be much greater than the dose from all sources of natural radiation others merged into one, larger than the dose received by patients undergoing radiation medical include examination with X-rays, and far greater than the dose of radiation of activity nuclear industry.

The Process of Asbestos
To better understand , here is a step in the process of asbestos. The first step is to do the milling to separate the fibers and clots. The second phase is in dry milling. On the basis of dry milling, there are several stages that is crushed by a jaw crusher or hammer crusher until a gauge of 150 mm, and then made hand sorting. then, sieved with a vibrating grizzly, wide spacing of 50 mm. Oversize crushed again by setting 50 mm, its products combined with undersize and dried at a temperature of 90-5400C for 1-10 minutes.
Minerals formed as a serpentine asbestos hydrothermal alteration (alteration) in ultra-alkaline rocks are rich in magnesia (peridotite, dunite). Only a few that occurs due to weathering magnesia limestone (dolomite). Asbestos can also occur because of changes in the form and process of transformation of the rocks. These include olivine rock called peridotite, composed of iron and magnesium silicates that experience temperature and pressure. Important to know what asbestos look like that you can also use asbestos safely.
The Types of Asbestos on Market
There are 4 types of asbestos on the market today include:
- chrysotile, or white asbestos
- amosite or brown asbestos
- Anthrophyllite or gray asbestos.
- crocidolite, or blue asbestos,
White asbestos is still used in the industry compared with asbestos brown and gray. Blue asbestos has been banned. Asbestos is a material that is sufficiently lightweight, fireproof and watertight. Broadly products of asbestos are heat-resistant clothing, coating the surface of the brake, clutch plate surface of the motor vehicle and textile coatings and construction materials. To know what asbestos look like, there are characteristic of asbestos. asbestos has refractory and acid resistant, shaped long or short fibers, easy twisted, robust, flexible, white, gray, green colors.
The properties of asbestos is fibers visible under a microscope straight corrugated, fiber surface is not rough that will be spun skid. Asbestos have physical properties. Asbestos fiber strength is depending on the species, mining and processing method. Asbestos heat is resistance at temperature of 100000C, the melting point 1180-150000C. Asbestos will lose weight if crystalline water and carbon dioxide evaporate. Chemical properties: chemical composition of the fiber is affected component.
Hopefully the article about types of asbestos and asbestos treatment can make you more aware of it, and you already understand the question that many people ask about what asbestos looks like.
