Keywords :
Feed Grade Precipitated Silica
PRODUCT DETAILS
1. Product Description
This feed grade precipitated silica is produced by the precipitation (wet) process from sodium silicate and sulfuric acid, yielding a hydrated, amorphous, hydrophilic white powder. Known as precipitated silica powder feed grade, white carbon black feed grade, precipitated silica white powder feed and feed grade amorphous precipitated silica, it is a feed grade hydrated silica and a hydrophilic precipitated silica for feed. With high purity and a precisely controlled porous structure, it is also a low dust feed grade silica and a free-flow silica powder feed grade, delivering reliable anti-caking, absorption and carrier performance for the feed industry.

3. Application Scope
As a precipitated silica feed raw material, feed grade silica fine powder and feed grade silicon dioxide bulk powder, this product serves feed manufacturing: it is a silica powder for feed manufacturing, an amorphous silicon dioxide feed additive and a non-crystalline silica feed additive. Its high oil absorption makes it a high oil absorption silica feed grade and a high adsorptive precipitated silica feed grade; its flowability makes it a free-flow silica powder feed grade and a low dust feed grade silica for premixes, concentrates, mineral mixes and feed carriers.

6. FAQs
Q1: What does 'precipitated' mean?
A: It means the silica is made by wet precipitation from sodium silicate and acid, forming a hydrated amorphous powder with a porous, high-absorption structure.
Q2: Is it crystalline?
A: No — it is amorphous (non-crystalline), which is the required, safe form for feed and food use.
Q3: Why is oil absorption important?
A: High oil absorption (240–300 ml/100g) means strong capacity to absorb liquids and convert them into dry free-flowing powders — key for carriers and anti-caking.
