Each tooth was then placed upon the reticulated zirconia in the thermal containment box and the technique of Microwave Hybrid Heating (MHH) was applied. The temperature measurements were taken every two minutes. We attempted to sinter the teeth in the microwave furnace with both fast and gradual heating rate (per minute) by manipulating the power rate. The power was increased gradually for few ...

Wear and corrosion has always had an adverse effect on the performance and service life of electrical arc furnaces. Every year, large amounts of money are spent on replacing the worn out parts of these furnaces which are no longer usable because of corrosion. One of the key causes of corrosion in electrical arc furnaces is the thermal radiation from the arcs. If the arcs are not properly covere...
