It\u2019s extremely fine-grained, sintered composition of high purity fused silica provides both outstanding wear properties and excellent thermal shock resistance. Special non-wetting properties, plus a factory coating of BN, prevent metal sticking and attack by aluminum and other molten metals.<\/p>\n<p>The lower thermal mass and conductivity minimize the chance of freeze-ups during the start or at low metal flow rates.
