Our molybdenum crucible is characterized by reliable quality, strong anti-oxidation and anticorrosion, high temperature resistance, quick heat conduction, high efficiency. With a working temperature among 1100℃, it’s applied in sapphire crystal growth, quartz glass melting, vacuum coating, rare earth smelting and other industries.
Vacuum-induction melting virtually always removes slightly less nitrogen than vacuum-resistance melting. The high oxygen value in vacuum-resistance melted- and-cast 4017 steel was probably due to a reaction between melt and crucible or the melt and the coated mold. This heat boiled violently when it was tapped, and the ingot surface was poor.
MOLYBDENUM CRUCIBLES FOR SAPPHIRE CRYSTAL GROWTH (LED) IN HIGH TEMPERATURE FURNACES. These high temperature materials are characterized by their high thermal and electrical conductivity, low coefficient of thermal expansion, and excellent strength and stability at temperatures above 2,000°C. Customer specific furnace components and fixtures for high temperature furnaces are uniquely designed and are supplied by . Starck.
So incorrect Ramp levels can definitely cause crucible cracking. The second reason is much easier - the user shuts the power supply off or has a very short ramp down time for power after the deposition is done. This causes the rapid solidification of the melt, and this stresses out the crucible liner.
Continuous Aluminum Melting and Holding Crucible Furnace. higher melt yield, and higher quality molten metal, required for this type of furnace. Time of starting up the furnace can be shortened by the light weight and higher thermal insulating furnace lining.

24p. Bottom-pour Ta and CaF/sub 2/-coated steel melt crucibles for Pu and Pu-rich alloys were developed. The controlled pour is effected by melting a Pu plug in the bottom spout of the crucible after the desired temperature and vacuum conditions are obtained.
Melting hence, casting efficiencies are low. In numerous heats a graphite liner was placed in the ladle.
