Why boron oxide is added while preparing ordinary glass?
urgent
What is the principal mineral used in making glass?
Glass is manufactured primarily from the mineral quartz (SiO2) which is what sand is made from. However small amounts of other minerals are added to the sand to make the process easier. These minerals are:- sodium carbonate (Na2CO3) lime (calcium oxide (CaO) magnesium oxide (MgO) aluminum oxide (Al2O3) There are also other minerals which are added to make specialised glasses. e.g. Pyrex glass is made from sand and boron oxide.
Boron nitride and aluminum oxide are both?
Both of these compounds are electrical insulators.
Why is B2O3 called boric oxide?
B2O3 has 2 Boron atoms and 3 oxygen atoms.
What type of glass is used in sodium vapour lamp?
there are two types of SVLs. LPS (Low pressure sodium lamps) these are also called sodium oxide (SOX) lamps and have two types of glass they have an outer vacuum envelope of glass coated with an infrared reflecting layer made of indium tin oxide, a semiconductor that lets visible light wavelengths to pass but reflects infrared light. then it has an inner arc tube made of borosilicate glass with Borosilicate glassBorosilicate glass is a type of glass with the main glass-forming constituents silica and boron oxide. Borosilicate glasses are most well known for having very low coefficient of thermal expansion , making them resistant to thermal shock, more so than any other common glass.-History:Borosilicate... solid sodium and a little bit of argon and neon gases as a "Penning Mixture" to start the gas discharge. HPS (High pressure sodium lamps) these lamps have other elements like mercury added. There is more chemical activity in these lamps resulting in higher pressure so the arc tube is often made of translucent aluminum oxide.
Element used in pyrex glass?
Pyrex is also known as borosilicate glass. It consists primarily of Silica and boron oxide. According to Wikipedia, typical borosilicate glass is composed of: 70% silica (silicone dioxide SiO2), 10% boron oxide, 8% sodium oxide, 8% potassium oxide, and 1% calcium oxide (lime). Wikipedia does note that some kitchenware glass marketed as Pyrex is actually soda lime glass. (see Wikipedia link)
What element makes Pyrex glass?
most glass starts with silica. the main element in pyrex that makes it so strong is boron. also there are trace elements of sodium potassium and aluminum oxide
Used in pyrex glass?
"Pyrex" is a brand name and is manufactured by Corning and is often different glass for different applications.Most commonly, Pyrex is a "borosilicate" glass. The first borosilicate glass was developed by Otto Schott in Germany and was called Duran. Other brandnames from around the world include Simax, Chinex, Kimble ...Glasses are known by their flux, a component which lowers the melting temperature of the silica sand which makes the glass, hence the name borosilicate denotes that the flux used is boron.So, basically, Pyrex is made from silica sand, boron (borax or boric acid), stabilising agents and decolourants as well as some other, minor ingredients.

What compound is boric oxide?
Boron oxide is used as a fluxing agent in the production of glass. For more see related links below.
What is is the formula for boron oxide?
The chemical formula for boron oxide is B2O3
What is the chemical formula for boron oxide?
The chemical formula for boron oxide is B2O3
What element is used in borosilicates?
There are a couple derivatives of elements that are used in borosilicate glass. They are boron oxide and silicon dioxide.
Which elements are used in manufacturing glass?
Silicon dioxide, or silica, is the major component of glass. It is also called "silica sand" or even just sand. There is nearly always other minerals or compounds is glass, and they vary greatly. Sand mainly contains the element silicon (Si).
What is the compound name for B2H6?
Boron hexahydride
What is the benefit of using boron oxide over boric acid in lining of induction furnace?
As per my knowledge Boric acid dissociates into Boron oxide by escape of water molecules from boric acid near to 300 deg centrigrade; hence bonding may be weakened. But in case of Boron oxide use, there is no dissociation of Boron oxide.
