High Temperature sintered silicon carbide crucibles up to 1,900 degrees Celsius (in a controlled atmosphere), and have good resistance to chemical erosions and thermal shock.

With its ability to accommodate temperatures as high as 1,650 C, significantly above the melting point of most alloys, it can be safely used without the risk of contaminating the molten metal. Our crucibles also offer superior mechanical strength at very high temperatures allowing them to be moved around safely for operations such as casting.

XICAR® Properties

Maximum temperature of 1650 °C in air and up to 1,900 °C in a controlled atmosphere

Maximum length up to 3,000 mm with a maximum OD of 300 mm

XICAR® thermocouple protection tubes are for both direct as well as indirect temperature sensing in molten metal (e.g. furnace wall or roof) temperature reading with Type R or S elements in molten brass, copper, cast iron, stainless steel or silicon metal

For temperature measurements in non-ferrous launders or pouring troughs

Better or equal quality than HEXOLOY SE tubes.
