![]() | How to Make Aluminum Oxide Boiling Chips (Al2O3) In this video I will show you how to make aluminum oxide for boiling chips. WARNING THIS PROCEDURE USES EXTREMELY HIGH TEMPERATURES. HAVE APPROPRIATE SAFTEY PROCEDURES AND USE FACE SHIELDS. First you will need some aluminum hydroxide I made in a previous video. Link below. www.youtube.com To make aluminum oxide you simply need to decompose the hydroxide by heating it very hot. I will be using a propane blow torch. I made a simple furnace by taking some bricks and staking them so I can heat the hydroxide easily and simply. Use the torch to heat the hydroxide It will start to flake apart as the water expands to steam. I heated for about 15 minutes. When you are done heating let the aluminum oxide cool and put in a labled bottle. Thanks for watching! 2012年01月29日再生回数 1034 |
![]() | Y10 Displacement: The Thermite Reaction - Fe2O3 + 2Al = Al2O3 + 2Fe From 20to9.com. Iron (III) Oxide + Aluminium = Aluminium Oxide + Iron. The thermite reaction is so exothermic that the reactio mixture reaches a temperature of over 2000 Celcius. Magnesium ribbon is used as a fuse to ignite the reaction.

![]() | Sapphire Etching Equipment, Sapphire al2o3 Wet Etching, High Temperature Quartz Tank www.imtecacculine.com Sapphire Etching & Beyond The Accubath Xe-Series was designed with Sapphire etching in mind but we know there are other processes that will benefit from the increased chemical reactivity that higher temperatures provide (300°C). Processes that were previously thought to be too slow due to temperature limitations may now be practical. 2011年04月15日再生回数 580 |
![]() | Crystallization of melts in system CaO-Al2O3. There are 8mm film from 1978 on the research of crystallization of melts in the system CaO-Al2O3. The research was made with the help of high temperature microscope in Institute of Silicate Chemistry. The small, about half of millimeter drop of melt were put into hole of Iridium foil that heated by electricity. Temperature of melt was up to 1900 C. After cooling of melt crystals start growing. Depend on temperature and content of melt there were variety of morphology and rate of growth of crystals. 2011年02月12日再生回数 398 |
