Stalactites and stalagmites consist of deposits of?
silica. +++ Wrong. They are of the mineral Calcite: crystalline calcium carbonate derived from the limestone above the cave.
Is helium corrosive?
No, helium is not corrosive.
Dacite is what type of?
A light gray volcanic rock containing a mixture of plagioclase and other crystalline minerals in glassy silica, similar in appearance to rhyolite.
Is bromine corrosive or combustible or flammable?
Bromine is Corrosive
What color is silica?
Silica is colorless.
What is silica dust?
Crystalline silica is a basic component of soil, sand, granite, and many other minerals. Quartz is the most common form of crystalline silica. Cristobalite and tridymite are two other forms of crystalline silica. All three forms may become respirable size particles when workers chip, cut, drill, or grind objects that contain crystalline silica.
Is Hardiflex II containing silica hazardous?
Any material containing crystalline silica is hazardous if its use or misuse results in release of the silica into the air that people could breath. If Hardiflex II contain crystalline silica it may be hazardous, if it contains amorphous silica, not.
How do you analyse crystalline silica respirable dust on a 37mm 10 micron filter?
You can analyse crystalline silica respirable dust on a 37 mm 10 micron filter by sampling.
Does quartz have healing powers?
No. Quartz is just crystalline silica. It does not have powers.
Are glass jars made from lime?
Glass is made from sand, however sometimes Quartz Stones are moulded into it for decoration.
When inhaled crystalline silica can cause scar tissue to form on what organs?
The Lungs
Crystalline silica can cause scar tissue to form on what organs?
The Lungs
What is silica made out of?
Silica is seen commonly in nature as sandstone, silica sand or quartzite. It is one of the most abundant oxide materials in the earth's crust. There are three crystalline forms of silica: quartz, tridymite, and cristobalite.
What health hazards can come from mica and silica?
The greatest hazard from crystalline silica (which is found in mica, among other materials) is a disease known as silicosis, caused by inhaling particles of silica.
Is it dangerous to inhale granite dust?
YES! - Crystalline silica is a basic component of soil, sand, granite, and many other minerals. Crystalline silica has been classified as a human lung carcinogen. Additionally, breathing crystalline silica dust can cause silicosis, which in severe cases can be disabling, or even fatal. The respirable silica dust enters the lungs and causes the formation of scar tissue, thus reducing the lungs' ability to take in oxygen. There is no cure for silicosis. Since silicosis affects lung function, it makes one more susceptible to lung infections like tuberculosis. REF: http://www.osha.gov/OshDoc/data_General_Facts/crystalline-factsheet.pdf
What is hardness of opal?
Opal is a hydrated amorphous form of silica; its water content may range from 3 to 21% by weight, but is usually between 6 and 10%. Because of its amorphous character, it is classed as a mineraloid, unlike crystalline forms of silica, which are classed as minerals Opal is a hydrated amorphous form of silica; its water content may range from 3 to 21% by weight, but is usually between 6 and 10%.

What is permissible exposure limit for respirable dust containing of crystalline silica as per NIOSH and ACGIH?
20 µg/m3
