What is a common refractory material?
Common refractory materials, materials that maintain their form even in high temperatures, are oxides of silicon, aluminum, and magnesium. The most refractory compound is hafnium carbide.
What are refractory materials?
They are materials , usually bricks, made with silicon oxides, that will withstand extremely high heat, without decomposition or chemical reaction. e.g. Blast Furnaces are internally lined with refactory bricks to with stand tha 1100 oC temperature of the furnace. The metal shell/chassis of the furnace would melt. Outside these refractory bricks is a water jacket to prevent heat escaping, into the outside environment.
What are metallic oxides?
metallic oxides are that type of oxides which contain metallic metals and oxides and which are cations like lithium, potassium e.t.c.
What are metal oxides with examples?
Metal oxides are oxides of metal. They are ionic in nature and form basic oxides. Eg: Na2O, MgO,etc
What are non combustible materials?
Most metals are considered non-combustible. In addition refractory and other oxides such as magnesium oxide, titanium dioxide, Zirconium oxide and materials such as cement, concrete, clays, soils, sand and ceramics are all non-combustible. There are many other substances too.
What are refractory oxides?
they are oxides that retains their physical strength at very high temperatures. this makes them suitable to be used as materials for things like crucibles and furnace linings. They can be subdivided into acidic, alkaline or neutral refractory oxides. an example is SiO2.
What is a common refractory material?
Common refractory materials, materials that maintain their form even in high temperatures, are oxides of silicon, aluminum, and magnesium. The most refractory compound is hafnium carbide.
What are the characteristics of oxide?
They are usually dull and brittle, form crystals and are insoluble (apart from potassium, sodium, lithium and ammonium oxides). Metal oxides are largely basic. Non-metal oxides are acidic. Aluminium and Zinc oxides are amphoteric (can act as a base or and acid by being able to both donate and accept protons.)
What do you mean by refractory concrete?
refractory Concrete means refractory castable == ==
Why did Yilong Refractory change their name into Changxing Refractory?
Because of Changxing Refractory's largest investment, Yilong Refractory was renamed as Changxing Refractrory.
Which of the following characteristics determines when the refractory period ends?
"how long it takes for the voltage-gated Na+ channels to reactivate at the end of an action potential"
How do you use refractory in a sentence?
1) The virus was refractory to the medication. 2) The refractory class was unable to get anything done.
Where you can get refractory concrete?

What is mag-dolo refractory?
magnesium-dolomite based refractory
Will the refractory product quality and services also change as the name of Yilong Refractory changed into Changxing Refractory?
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.
Is the neuron ready to fire during the refractory period?
Refractory period
What is refractory insulation?
Refractory insulation is defined as insulation for extremely high temperatures. The threshold of temperature of insulation for refractory insulation is > 815 Celsius.
