CK 105Z42 Ceramic Cup (5/16" x 1-27/32") xref: 3C5

Ceramic (lava) cups are recommended for use in applications where high reflective heat is present. Alumina nozzles tend to break when used in confined areas or when high reflective heat is present. If this type of usage is contemplated, we recommend the use of ceramic (lava) cups. When alumina nozzles are fired in the oven at 3000? F during manufacturing, they shrink 18% in length and 27% in diameter. If the nozzle is subsequently used in a confined area, excessive heat is transferred back into the nozzle causing it to expand. Cooling shrinks the nozzle back to normal. The large difference between expansion and contraction results in breakage. Package of 1
