Crucibles
Precision-engineered ceramic crucibles for high-temperature applications and demanding industrial processes
Advanced Ceramic Crucibles
Henson Ceramics Limited has developed a range of crucibles in a variety of materials to suit almost any application. These products, which may be slip-cast or isopressed, are available in a range of sizes from a few millilitres to several litres.
Typical uses are for high temperature calcinations (>2000°C), molten glass/metal processing, rapid thermal cycling (rotary kilns), and gemstone purification for the jewellery industry.
Whilst the majority of applications require the ceramic to be impervious, porous forms of most sizes are available on request.
