Applications
The Verneuil process:
Around 1890 Auguste Verneuil developed a method for synthesis of semi-precious stones known as 'fusion'. This process uses an oxyhydrogen burner through which alumina is sprayed which melts and falls onto a seed crystal, recrystallized by cooling into a single crystal. A 'bottle or carrot' (in red on the diagram) is formed as the alumina is injected and the crystallization frond is kept at a constant distance from the flame.
CTI offers manufacturers using this process a full range of insulation products from around the reaction.
