Addition of silicon caused the reduction in milling time and resulted in finer (5 ± 1.2 µm) and uniform powder particles. No major changes in sinterability have been observed in both the alloys. XRD analysis confirmed the austenite and martensitic formation from the ferrite matrix in Si-free ODS steel.

Calcium Carbide - an overview | ScienceDirect Topics

Major producers manufacture acetylene by either the partial oxidation of natural gas or as a coproduct of the thermal cracking of ethylene; minor producers manufacture acetylene from calcium carbide. About 80% of production is used as a closed system intermediate in the manufacture of acetylene black as well as acetylenic and vinyl derivatives used in a variety of appliions such as the manufacture of plastics.

Phenol substituted polymethylsilane: a soluble …

2015/1/24· Polymethylsilane (PMS), with structure of [–SiH(CH 3)–] x, has been widely used as precursors to product silicon carbide ceramics. However, its appliion is limited by two drawbacks. Synthesis of PMS is so rigorous that only a few functional groups (such as phenyl, alkyl, etc.) could be introduced into Si–Si main chain, which limits the functionality of PMS [ 8 – 10 ].
