Fused Silica Brick by Luoyang Maile Refractory Co Ltd

Silica bricks are the main species of silicabased refractories where the mass fraction of sio2 is not less than 93 Silica brick is a typical acid refractory bricks the acid slag has a good resistance to al2o3 feo fe2o3 and other oxides also has good resistance but the resistance to alkaline slag is poor easy to cao k2o na2o and other oxides and damage

Explain the preparation properties and uses of silica bricks

Silica bricks are fired at temperature of about 14501500 deg C with longer holding times being required at the highest temperatures For this reason firing in annular kilns or bogie hearth furnaces are preferred Because the transformation of the silica modifiions takes place suddenly cooling must be carried out slowly or the bricks will

Properties of Silicon Dioxide Science Struck

Silicon dioxide or silica as it is commonly known as is an important constituent of sand However it is found in several other forms too In this article we shall look into the physical and chemical properties of silicon dioxide and learn a little
