Fumed Silica for Ceramaspeed

RFQ Description

SPECIFICATION REQUIREMENTS1. BET Surface area 90 (+25 / -15) m2/g2. Tamped density maximum 60 g/l3. Moisture content (2 hours at 105oC) 1.5 %4. pH (in 4% aqueous dispersion) 3.8 to 4.6 (Ensuring that the Cl content is 100 ppm)5. Loss on ingition (2 hours at 1000oC) 1.5%6. 325 Mesh residue 0.04 %7. SiO2 content 99.8 %While this spec is our prime material we can use what we call non prime which is material not quite within this spec. This normally means how dense the material is and I believe the process of manufacturing Silica means the first off pallets can be out of spec.Could you let me know the following?1) Can you supply material within the specification attached?2) Do you have material that is out of this specification? If so how much? What are the differences?3) If yes to either 1 or 2 how much do you have?4) What are you thoughts on transport to Laredo in the USA and associated costs?5) What packaging is this material in? Please let me know if you need any more information to complete a quote. Thank you for your time.Best Elsy OcejoProcurement Specialist fumed silica, 90, 200 Fumed Silica, Rutile Sand, Vermiculite
