Silicon dioxide is suitable for lining furnaces because of its very high melting point of 1,600 to 1,725 degrees celcius. It is so high because of the strong intermolecular forces between SiO2 molecules in the giant covalent structure comparable to that of diamond and graphite. A large amount of energy is required to overcome these intermolecular forces and thus SiO2 has a high melting point.

Note: no silicon-oxygen bonds are broken during melting, just intermolecular forces between SiO2 molecules.

Magnesium oxide as a refractory lining material?

Magnesium oxide is used to make linings for some furnaces. It is known as a refractory material - which just means that it is resistant to heat.Magnesium oxide has a high melting point (2852°C) and so resists the high temperatures in a furnace. Its melting point is high because of the strong ionic bonds between the small Mg2+ and O2- ions.


What is freeze-lining of a furance in smelting area?

Freeze-lining refers to the accumulation of solidified material, such as slag or metal oxides, on the refractory lining inside a furnace in the smelting area. This can obstruct the flow of material and heat transfer, leading to decreased efficiency and potential damage to the furnace lining. Regular maintenance and proper operating conditions can help prevent freeze-lining issues.


Why is silica used to make bricks for high temperature furnaces?

This is because silica has a high melting point due to its giant molecular structure. To break it up you would have to break strong covalent si-O bonds. I stumbled across this as i was trying to do my chemistry assessment. Hope it helped :)


What is fire sand?

Fire or furnace sand is generally coarser than the sand used in metal molding. It is used in building floors for acid open-hearth furnaces and in lining the cupolas and ladles that contain molten metal in the foundry industries.


How do you take off adhesive sticker from lining in shoes?

You can use rubbing alcohol or nail polish remover on a cotton ball to help loosen the adhesive. Gently rub the sticker to slowly peel it off the lining of the shoe. Be careful not to damage the shoe's material while removing the adhesive.

Where are you use double shoe brake?

A double action brake shoe comprising a shoe, a lining and an oscillator material as main components which function respectively as a reinforcing body of the brake shoe, a brake material and as a generator of certain vibration frequency when the shoe is applied to a hub. The lining is attached on the surface of the brake shoe and oscillator material is inserted between the shoe and the lining.


What do lining and noliving thing have in common?
