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.
What else can I help you with?
Is silicon dioxide a homogeneous or heterogeneous?
Silicon dioxide is a homogeneous mixture, as it is a compound composed of silicon and oxygen atoms uniformly distributed throughout the material.
Is silicon dioxide an insulator?
Yes, silicon dioxide is an insulator. It is a material commonly used in the production of insulating layers in electronic devices due to its high resistivity and ability to block the flow of electric current.
What is the balance of silicon reacts with carbon dioxide form silicon carbide and silicon dioxide?
The balanced chemical equation for the reaction between silicon and carbon dioxide to form silicon carbide and silicon dioxide is: 3Si + 3CO2 -> SiC + 2SiO2
What is the percentage composition of silicon dioxide?
Silicon dioxide is composed of 46.7% silicon and 53.3% oxygen by mass.
Is silica the same thing as silicon dioxide?
Silicon is just silicone and silicone dioxide is one part silicon to every two parts oxygen.
Why is silicon dioxide used as the layer of furnaces?
Silicon dioxide is used as a layer in furnaces because it acts as an insulator, helping to retain heat and improve energy efficiency. Additionally, it has a high melting point, which allows it to withstand high temperatures in furnaces without degrading. Silicon dioxide also has good chemical stability, making it resistant to reactions with the materials being processed in the furnace.

How is silicon useful for humans?
Silicon, as the dioxide, is the main component of glass. It has been suggested that silicon could be used as a fuel. First being reduced in solar furnaces near the equator, and then oxidized again at the energy consumption point.
What are the differences between Silicon Dioxide and Diamond?
Silicon dioxide is a compound composed of silicon and oxygen atoms, while diamond is a pure form of carbon arranged in a crystalline structure. Diamond is the hardest naturally occurring material, while silicon dioxide is not as hard. Additionally, diamond is a valuable gemstone, whereas silicon dioxide is commonly found in materials like sand and quartz.
Can silicon burn in the air?
Silicon does not burn in the air because it is a non-combustible material. It can react with oxygen at very high temperatures to form silicon dioxide, but this is not a combustion reaction.
The structure of silicon dioxide consists?
Silicon dioxide has a tetrahedral structure where each silicon atom is covalently bonded to four oxygen atoms. This forms a three-dimensional network of SiO2 molecules, creating a hard and brittle material. Silicon dioxide is commonly found in nature as quartz or as a major component of glass.
Which mineral is composed of silicon dioxide?
Quartz is composed of silicon dioxide.
Is silicon dioxide reactive?
silicon dioxide is reactive when eating egg
Is silicon dioxide an insulator?
Yes, silicon dioxide is an insulator. It is a material commonly used in the production of insulating layers in electronic devices due to its high resistivity and ability to block the flow of electric current.
What does the structure of silicon dioxide consist of?
The structure of silicon dioxide consists of silicon atoms bonded to four oxygen atoms in a tetrahedral arrangement. These tetrahedra link together to form a three-dimensional network structure, resulting in a rigid and crystalline material. Silicon dioxide can exist in different forms such as quartz, amorphous silica, and glass, depending on the arrangement of its atomic structure.
What are common compounds found in silicon?
Common compounds found in silicon include silicon dioxide (SiO2), silicon carbide (SiC), and silicon tetrachloride (SiCl4). Silicon dioxide, in the form of quartz or sand, is the most abundant compound and is used in making glass and ceramics. Silicon carbide is a hard material used in abrasive products and cutting tools, while silicon tetrachloride is a precursor in the production of silicon metal.
