Every article here ends in a grade
The notes explain why microsilica behaves the way it does. This is the short way from those notes to the material — pick what you are making, and we will send the data sheet and a price for that grade.

Sichuan Ewende New Material Co., Ltd. collects silica fume where it is made — alongside ferrosilicon and silicon-metal furnaces in Qinghai, Gansu, Ningxia, Shaanxi and Inner Mongolia. Bag-house filters pull roughly 7,100 tonnes of powder out of the off-gas every month, and it is packed at source rather than traded through a warehouse.
Buyers usually call us after one of three things has happened: the SiO₂ content drifted between batches, the powder arrived caked with moisture, or nobody answered when a shipment slipped. All three are process problems — and they are solved at the furnace, not at a trader's desk.
