It can have different meanings, depending on how it is used. A common meaning of refractory is a type of concrete intended for use in very high heat conditions, such as the inside of a furnace. These materials must be cured (allowed to "set up") at controlled temperatures before being exposed to very high temperatures.

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.
The relative refractory period is the time when a neuron can respond to a stronger stimulus, while the absolute refractory period is when a neuron cannot respond at all. The relative refractory period follows the absolute refractory period and allows for increased neuronal excitability.
Refractory insulation is defined as insulation for extremely high temperatures. The threshold of temperature of insulation for refractory insulation is > 815 Celsius.
The refractory period is the time after a neuron fires when it cannot fire again, while the absolute refractory period is the specific part of the refractory period when the neuron is completely unable to fire, regardless of the stimulus.
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.

If you mean like, on boolprop it means cure vampire. But, you have to be a vampire to cure one.
