What compound is boric oxide?
Boron oxide is used as a fluxing agent in the production of glass. For more see related links below.
How to make zinc borate?
Heat Zinc oxide and Boric acid (Boric powder) in water.
What is cobalt glass?
cobalt glass is glass containing cobalt oxide or cobaltous oxide as a colouring agent. These oxides give the glass a blue colouring.
Is boron oxide acidic or basic?
Boron oxide, B2O3, is acidic. It reacts slowly with water to form boric acid. When fused, (molten) it reacts readily with metal oxides to form borates.
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 is the name for this formula B2O3?
Boric Oxide.
How to make zinc borate?
Heat Zinc oxide and Boric acid (Boric powder) in water.
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.
What is the chemical formula of boric oxide If B203 is listed as Barium Oxide which I thought tow BaO then what is Boric Oxide which I thought was B203?

What mass of boric oxide is formed from the decomposition of 10g BOH3?
5g of boric oxide because BOH3 is twice as big as Boric oxide so half as much as formed. it is also relative to the atomic mass of C12. Taken from text book by Dr. Rory Moloney and Dr. Fran Molloy. Hope this helps you in your quest from chemistry knowledge.
What makes pyrex glass heat resistants?
PYREX (TM) is a borosilicate glass with a very low coefficient of thermal expansion (3.3 x 10−6/K - about one-third that of ordinary glass). The boron (or boric oxide) in the matrix apparently helps moderate the effect of changes in temperature so that even when it undergoes large changes in temperature, it doesn't expand or contract as much as normal silicate glass; normal glass will crack when exposed to big temperature changes. In this respect it has good heat resistance. It is also very chemically stable with temperature - again a "heat resistant" characteristic. Finally, it has a high melting point (~820 °C or 1,510 °F) so it tolerates oven temperatures quite well.
Why is B2O3 called boric oxide?
B2O3 has 2 Boron atoms and 3 oxygen atoms.
What is fine crystal?
Fine crystal is considered high quality glass. In order for the product to be classified as crystal rather than glass, at least 10% lead oxide has to be present.
What is cobalt glass?
cobalt glass is glass containing cobalt oxide or cobaltous oxide as a colouring agent. These oxides give the glass a blue colouring.
Is glass from a renewable source?
Strictly, no. Renewable is usually applied to something like the energy from sunlight or wind, which is still there tomorrow even if we use it today.However, glass is made from silicon (very clean sand, but not rare) with a mixture of added chemicals (soda, lime, antimony oxide etc) to improve the quality. Calumite is also usually added.And of course an important ingredient now is cullet, which is broken recycled glass, which makes glass somewhatrenewable.
Is boron oxide acidic or basic?
Boron oxide, B2O3, is acidic. It reacts slowly with water to form boric acid. When fused, (molten) it reacts readily with metal oxides to form borates.
