Refractory oxides are a group of metal oxides that have high melting points and are resistant to heat and chemical reactions. These oxides are commonly used in high-temperature applications like ceramics, refractory materials, and thermal coatings due to their ability to withstand extreme conditions. Examples include alumina (Al2O3), zirconia (ZrO2), and silica (SiO2).
Yes, oxides are extensively used in various industries. For example, titanium dioxide is used in paints, cosmetics, and food products; aluminum oxide is used as an abrasive in sandpaper and as a refractory material; and iron oxide is used as a pigment in paints and ceramics.
Amphoteric oxides are oxides that react with both acids and bases to form salts and water only. Some examples of amphoteric oxides include aluminum oxide (Al2O3) and zinc oxide (ZnO).
Oxides can be classified into acidic, basic, amphoteric, or neutral based on their chemical reactivity with water. Acidic oxides react with water to form acids, basic oxides react to form bases, amphoteric oxides can act as both acids and bases, while neutral oxides do not react with water to form either acids or bases.
Oxygen can form two types of oxides: basic oxides, such as magnesium oxide, and acidic oxides, such as sulfur dioxide.
The symbol for nitrogen oxides is NOx.
Refractory oxides have high melting points, excellent thermal stability, and resist chemical corrosion at high temperatures. They are commonly used in furnace linings, crucibles, and other applications that require resistance to extreme heat and harsh environments.
A common refractory material is alumina, which is an oxide of aluminum. Alumina has high temperature resistance and is commonly used in industrial furnaces and kilns due to its ability to withstand extreme heat.

Because of Changxing Refractory's largest investment, Yilong Refractory was renamed as Changxing Refractrory.
1) The virus was refractory to the medication. 2) The refractory class was unable to get anything done.

The only change of Yilong Refractory is its name which has changed into Changxing Refractory. Its product quality, pre-sale and after-sale services remain unchanged.
Refractory insulation is defined as insulation for extremely high temperatures. The threshold of temperature of insulation for refractory insulation is > 815 Celsius.
refractory period is the interval between action potential , the absolute refractory period is the period in which second action potential can not be initiated but in relative refractory period the second action potential can be initiated by the more strong stimulus.

Super Refractory is a refractory material which retains its shape and chemical identity in extreme heat, so super refractories are used in Industries for heat resistance.
