Ferrosilicon grains are small particles broken and screened by natural and standard blocks of ferrosilicon in accordance with various particle sizes, and the specific content and particle size will vary due to different production methods and uses.
Specifications of ferrosilicon grains
In general, the silicon content of ferrosilicon grains varies according to the variety, for example, the silicon content of FeSi90 is between 87% and 95%, the silicon content of FeSi75 is between 72% and 80%, and the silicon content of FeSi65 is between 63% and 68%. There are also low silicon iron particles containing less than 60% silicon.
There are differences in the use and usage of different content of ferrosilicon particles, which is also a problem that needs to be paid attention to when purchasing.
The size of ferrosilicon grains
In addition, regarding the particle size of ferrosilicon grains, the particle size range of ferrosilicon particles is usually 0.2 to 15 mm, or customized according to customer requirements.
For example, the particle size requirements are usually: 0.2-0.8mm, 1-3mm, 3-8mm, 8-15mm and other standards.
The specific particle size selection is based on the needs of the specific application, for example as a casting material, different particle sizes of ferrosilicon may be required to meet the needs of the casting process.
Purchasing precautions of ferrosilicon grains
Choice of supplier or manufacturer
It is important to choose a supplier or manufacturer with a good reputation and reliable quality. Suppliers should be fully investigated and evaluated, including reviewing their business licenses, production licenses and other relevant qualifications, to understand their production scale, technical strength and product quality control system. Avoid selecting unqualified or disreputable suppliers to avoid purchasing inferior products.
Product quality
Define the specifications, quality standards and purity requirements of the required ferrosilicon particles. Ensure that purchased ferrosilicon pellets meet production requirements to avoid production interruption or substandard product performance due to quality problems.
Price and cost performance
While price is an important consideration, low prices should not be pursued alone. The quality of the product, the reputation of the supplier and the service should be considered comprehensively, and the cost-effective products should be selected. Avoid being deceived by suppliers with inflated prices, leading to unnecessary costs.

Delivery time and stability
Clarify the delivery time with suppliers and ensure that they can deliver on time. For the situation that requires long-term stable supply, suppliers with stable supply capacity should be selected to avoid affecting the production schedule due to unstable supply.
Contract and Terms
When signing a procurement contract, the terms of the contract should be carefully reviewed to ensure that the rights and obligations of both parties are clear. Pay special attention to the terms related to product quality, delivery time, after-sales service, etc., to avoid disputes in the later stage.
Transportation and storage
Consider the transportation mode and storage conditions of ferrosilicon grains. Select the appropriate packaging and transportation methods to ensure that the silicon particles are not damaged during transportation. At the same time, ensure that the storage environment is dry and ventilated to avoid moisture or deterioration of iron silicon particles.
Precautions for the use of ferrosilicon grains
Avoid moisture and direct sunlight
When storing and using ferrosilicon grains, they must be protected from moisture and direct sunlight. Moisture may cause agglomeration or deterioration of iron silicon grains, while direct sunlight may trigger chemical reactions of iron silicon grains or accelerate their oxidation.
Ensure good ventilation
The use of iron silicon particles should be carried out in a well-ventilated place and avoid operation in a closed environment to reduce the concentration of dust produced by iron silicon particles in the air, thereby reducing the risk of inhaling harmful substances.
Wear protective gear
Wear protective equipment such as protective gloves, face mask, and goggles when handling ferrosilicon particles to prevent splash or dust on the eyes, skin, and respiratory tract.
Avoid contact with toxic and harmful substances
During the storage and use of iron silicon particles, contact with toxic and harmful substances should be avoided to prevent chemical reactions or pollution.
Emergency treatment
If accidentally contact with iron silicon particles or inhalation of its dust, should immediately stop the operation, and take appropriate emergency measures, such as cleaning the contact site, breathing fresh air, if necessary, timely medical treatment
Standardize operation
Use ferrosilicon grains correctly according to operating procedures to avoid safety accidents caused by improper operation.
