For the preparation of high temperature mechanics experimental furnace, has been recommended by electric heating elements, it is because it has a good controllability, reliability and clean. MoSi2 most can meet the performance requirements, and has good adaptability and high maneuverability. When manufacturing functional ceramic sintering (firing or sintering) is a critical step.
For engineering ceramics manufacturing, more strict temperature control, the accuracy and reproducibility control requirements to achieve the requirement of the product structure and performance. These are for the synthesis of MoSi2 heating elements and manufacturing put forward strict requirements, not only requires the composition of molybdenum disilicide (MoSi2) conform to the chemical metrology, and dense structure requirements, performance has certain strength requirements, etc. Therefore, for various ceramic materials manufacturing in terms of cost, the sintering is the highest one.
Molybdenum alloy
It is reported that the share accounted for about half of the total cost (including quality control, QC and yield), however, for metal materials, the sintering cost usually < 10% of the total cost.
Sintering requirement is different with different applications. For example, to research and development of sintering furnace requirements under various atmosphere has a wide range of temperature control. When engineering control, until the batch or continuous production, using the same type of element is good. For ceramic material mechanics experiment, often requires high temperature. The standard test, the ideal condition is reliable, it is obvious that each test of constant temperature, and devices easy to use.
