I had an interesting experiment yesterday. This was my first time using a triac to regulate input power and sealing the tube with a compression fitting. Unfortunately, my thermocouple failed.
Take a look at the alumina tube and the evidence for melting. The furnace sealant which I coated it with completely melted and agglomerated to the bottom of the cell (also appears to be mixed with melted alumina). http://www.lenr-coldfusion.com/wp-content/uploads/2015/03/IMG_20150317_084823_361.jpg The tube was purchased from China and is purportedly 95% pure. It was supposed to have a continuous operating temperature of 1500C. Any opinions? Jack
