The impact of temperature applied to the quartz crucible is critical for optimum performance.

Coefficient of Expansion
Coefficient of expansion is defined as the increment of length in a unit of length for a rise in temperature of one degree. The coefficient of thermal expansion for quartz is dependent on the application temperature.

|
Thermal Diffusivity
Rate of heat diffusing through a unit area per unit time.
|
|
Heat Capacity
The heat capacity of a material is the amount of heat transferred to raise a unit mass of a material one-degree in temperature.
|
|
Thermal Conductivity
The thermal conductivity of quartz material varies with temperature, and mean thermal conductivity is defined by a constant factor K.
|
|
Viscosity
Viscosity is the measure of the resistance to flow of a material when exposed to a shear stress. Since the range in "flow-ability" is extremely wide, the viscosity scale is generally expressed logarithmically.
