refractory minerals are those minerals that contain refractory materials or elements. few example will make it clear but let us know what is refractory material. simply a material that can resist high temperature or pressure is a refractory material. e.g magnesium, zircon, etc. ASTM- American Society Of Testing Material defines the range of the temperature to be 1000 F and above that a material can tolerate to be refractory. so those mineral from which we can extract or is composed of refractory element are called refractory minerals( please see the definition of mineral). The major significance of these mineral is that they can produce such element or material that can be used as catalyst, in blast furnace, and in high temp. zone. was the ans satisfactory.

What is the relationship between the relative refractory period and the absolute refractory period in terms of neuronal excitability?

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.

What is the difference between the refractory period and the absolute refractory period in terms of neuronal signaling?

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.


2 Define refractory period and differentiate between absolute and relative refractory periods?

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.
