Silica is like Carbon, Basically its atoms form strong covalent bonds between each other(4 as they each have 4 electrons in their outer shell) these bonds are branched in a never ending pattern, many of these strong bonds have to be broken in order for Silica to melt and hence it has a high melting point
What else can I help you with?
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 substance has a high melting point?
One substance that has a high melting point is diamond.
Does silicon have a high melting point?
Yes, it has a melting point of 1683 Kelvin.
Does argon have a high melting point?
No, it is very low. Argon has a melting point of −189.3°C
Naphthalene has high or low melting point?
Naphthalene has a relatively low melting point of around 80 degrees Celsius.
What is the melting point of silica crucibile?
The melting point of silicon dioxide is in the range 1 600-1 725 0C.

Does carbon have high melting point?
it has a low melting point
Does a metal have a high or low melting point?
All metals have different melting points but they are all high
Do solids have a high or low melting point?
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
Does chromium have a high low melting point?
Chromium has a high melting point of 1,857°C (3,375°F) making it a refractory metal.
How does the coposition of the magma affect the temperature at which it solidifies?
The composition of the magma is very important for solidificatoin temperature. When it starts to cool, crystals of minerals begin to grow. If it has a low silica content - which means high melting point - the magma will solidify at high temeratures. If it has a high silica content - which means low melting point - it will solidify at lower temperatures.
Does silicon have a high melting point?
Yes, it has a melting point of 1683 Kelvin.
How can reduce silica sand melting temperature?
Assalam walykum, guys as well as I know Soda Asia Sodium Carbonate reduce the melting point of silica sand about 1600 degrees to 750 degrees, but I don't know what is the percentage of it......
Is 63.38 c considered a high melting point?
No, this is a low melting point.
Do alkynes have high melting point?
For example the melting point of acetylene -80,8 oC.
