Low Form Quartz Crucible can be transparent or milky white. Transparent Quartz Low Form Crucible can withstand up to 1100 degree centigrade. It is most important to note that Quartz Low Form Crucible can withstand very high thermal shock (1000 degree centigrade to room temperature).
This transparent quartz is obtained through different types of raw materials because that includes natural or synthetic quartz sand. These are highly resistant to thermal shock due to the extremely low coefficient of thermal expansion because they have excellent electrical strength that offers stability under temperature variation.
Our range of Low Form Quartz Crucible is developed in our company by using high purity fused quartz as raw material and fabricating with advanced ceramic technology.
Thermal Properties of Quartz Crucible
Thermal Conductivity 1.38(W/m°K) Coefficient Of t\Thermal Expansion(0~1000 °C) 0.55(10 -6/ °C) Normal Operating Temperature (Continuous Usage) ~1050 °C Normal Operating Temperature (Non-Continuous Usage) ~1250 °C Strain Point ~1075 °C Annealing Point ~1180 °C Hot Pressing Temperature ~1700 °C – 2100 °C Devitrification Temperature Starting at ~1000 ° C. high temperature accelerates Devitrification, especially with surface contaminants such as alkaline solution, salts and vapours.
