Silicon Metal Powder For Chemical Casting

High-Purity Material
The product uses high-grade Si553/Si441 silicon with ≥98% purity and ≤0.3% impurities, ensuring clean reactions and dense castings.

Excellent Flowability
With a 50–800 mesh size range and uniform round particles, the powder flows smoothly for efficient and even mold filling.

High-Temperature Stability
Refined silicon powder remains stable below 1600°C without agglomeration or decomposition, ensuring casting precision.

Enhanced Bonding Strength
The powder bonds tightly with metal matrices, improving compressive strength by 20–30% and extending service life by about 40%.

Silicon-Based Alloy Preparation
Silicon metal powder can be fused with aluminum, iron, and other metals to produce high-strength, corrosion-resistant silicon-based alloys, widely used in aerospace and automotive engine components.

Electronic Ceramic Materials
Silicon metal powder for chemical casting can be used in the production of semiconductors and ceramic substrates, improving conductivity and high-temperature resistance, and is an important raw material for electronic packaging materials.

Metalized Coatings
Combined with resins or metals, it can be used to coat casting surfaces, enhancing wear resistance and oxidation resistance.

Silica Sol and Refractory Materials
Silica Sol powder can be made into silica sol for use in refractory castables and high-temperature protective coatings, enhancing thermal stability and structural strength.

Chemical Reducing Agent
It can be used as a reducing agent in chemical casting to reduce metal oxides to pure metal.

High-Temperature Lubricants
Fine silicon powder can be combined with graphite or ceramics to form high-temperature lubricants, reducing metal friction and wear.
