Upcycling Polysilicon into Ferrosilicon Powders
Pot scrap, crops, broken wafers and sawing kerf are already-reduced silicon at six-nines purity or better. What that buys a welding or DMS customer, and the four things that make the…

Notes from the plant
Short technical articles from our production and R&D team on the materials that go into welding consumables and steel making.
Ferro Chrome: One Ore, Two Opposite Jobs
Keep the chromium dissolved and you get stainless steel. Precipitate it as carbide and you get a wear part. Carbon is the switch.
Read articleWhich Ferroalloy Goes Into Which Welding Consumable
A sourcing matrix mapping every common ferroalloy and metal powder onto the AWS electrode and cored wire classifications — from E6010 to hardfacing overlay.
Read articleThe Role of Metal Powders in Powder Metallurgy
Every property of a sintered part — density, strength, precision, cost — is set by decisions made about the powder long before it reaches the tool.
Read articleFerro Manganese in Steelmaking: Three Jobs, One Addition
Deoxidation, desulphurisation and alloying happen simultaneously — and the grade you should buy is decided by carbon, not by manganese.
Read articleFerro Silicon 45%: Sold as a Commodity, Used as a Specialty
Why welding electrode plants buy 43–47% Si and never 75%, what “stabilised” actually does inside a silicate binder, and how particle shape decides whether a batch survives the bake.
Read articleFerro Silicon 15%: The Grade You Buy for Density, Not Chemistry
Why the dense medium industry settled on 14–16% silicon, what atomized really buys you over milled, and why the price per tonne tells you almost nothing about the cost.
Read articleHow to Specify and Buy Ferroalloy and Metal Powders
Most supply disputes are not about quality — they are about ambiguity. Here is what a complete specification contains, and the five clauses that prevent almost every argument.
Read articleFerro Manganese in Welding Consumables: The Element With the Narrowest Window
Manganese decides weld metal toughness, prevents solidification cracking, and is now the element under the most regulatory pressure in the industry. Getting it right starts with the powder.
