Magnesium Oxide Prill Beads

RFQ Details

Approx 100kg Magnesium Oxide Prill Beads. Irregular in shape and fairly small (more surface area). These are for conditioning of water conditioning (leave them in a jug of water to improve alkalinity). We can go more than 100Kg but not into metric tons. A couple of buckets full would be ideal.I am told that they are kiln fired to prevent them from dissolving when added to water, but have no way to verify that. I've also been told they're fired in clay. Delivery is to Thailand.
