When quartz is heated, it becomes transparent to infrared radiation.
This allows the energy generated by a heating element to be transmitted directly to the target without being absorbed by the quartz itself.
This makes quartz heaters more efficient than ceramic heaters.
Quartz heaters can target specific areas and do not rely on convection heating.
The energy produced by quartz heaters goes directly to the target without losses to the surrounding air.
5 Key Insights
1. Transparency to Infrared Radiation
The efficiency of quartz heaters is due to their ability to transmit infrared energy without absorption.
Quartz is essentially transparent to infrared radiation.
This means that the energy generated by the coiled wire heating element, typically made of an iron-chromium-aluminum alloy, is not absorbed by the quartz.
Instead, it is transmitted through the quartz tube directly to the process or target.
2. Efficiency Over Ceramic Heaters
Quartz heaters are more energy-efficient than ceramic heaters.
They consume less energy to produce the same results.
This is because the majority of the energy produced by quartz heaters goes directly to the product in the form of infrared energy.
This is in contrast to ceramic heaters, which rely on convection heating and lose a portion of their heat to the surrounding air.
3. Targeted Heating
The targeted nature of quartz heaters allows for more precise heating.
Convection heat produced by ceramic heaters will go wherever the air currents in the process go.
Quartz heaters, however, direct the heat more accurately to the desired area.
4. High Purity Quartz
The high purity of quartz used in the manufacturing process contributes to its superior optical and thermal properties.
Fused quartz tubes are made by fusing or melting naturally occurring quartz crystals at high temperatures.
This results in a material that is transparent and has excellent thermal and optical properties.
5. Temperature Monitoring
However, it is important to note that quartz pollution can have an effect on the thermocouple over time.
This can result in lower temperature readings and higher firing temperatures.
It is crucial to monitor the temperature throughout the heating process to ensure consistency and accuracy.
