Notes to the table:

1. *Water absorption for fillers of classes 7-11 (ZShA, ZShB, ZShV, ZShK 1, ZShK 2 and ZShB 1 grades) is not standardized.

2. For fireclay filler: ZSh-1.3 grade - bulk density, g/cm3, NMT - 1.3; ZSh-0.6 grade - bulk density, g/cm3, NMT - 0.6. 

3. For ZMKR-0.8 mullite silica filler grade - bulk density, g/cm3, NMT - 0.8. 

4. For ZML-1.3 mullite filler grade - bulk density, g/cm3, NMT - 1.3.
