Nuclear Grade Boron Carbide 36 Micron

Sandblastingabrasives.com SKU: B4C NG 36L

This fine B4C powder is most commonly used as an additive to concrete.  External, 3rd party NQA certs available at added cost.  This item cannot be purchased on-line.  Our internal cert lists the B4C Type III specification for Total Boron as 70% min – 81% max.  The actual Total Boron content as reported will likely be higher than 76% but the guarantee for Type III is for 70% min.
