WebTwo step fused silica production. In this process, soot is deposited on a rotating bait rod (outside vapor deposition; OVD) or on the end of a rod that is pulled upwards (vapor axial deposition; VAD). The soot accumulates and forms a porous body with a density that is less than 25% of that of fused silica. This porous body is then vitrified in ... WebSilica fume is an ultrafine material with spherical particles less than 1 μm in diameter, the average being about 0.15 μm. This makes it approximately 100 times smaller than the average cement particle. The bulk density of silica fume depends on the degree of densification in the silo and varies from 130 (undensified) to 600 kg/m 3.The specific …
