heat conductivity of zircon

thermal conductivity of zircon sand - gogreen-now.eu. ZYP Yttrium Oxide products have low thermal conductivity. Yttrium oxide has one of the lowest thermal conductivities of refractory oxides at high temperatures (0.007 cal/cm-sec-K at 1400 C). This property allows yttrium oxide to be used to reduce the heat flow on many substrates.
