<p>Fluid permeable wall members through which an auxiliary fluid is passed against pressure exerted by a fluid to be contained, which wall member is composed of inorganic fibres, may be used to contain hot fluids or fluids otherwise having a deleterious effect on the wall members. Vacuum formed shapes composed of refractory inorganic fibres may be used to contain fluids having temperatures of over 2500 DEG C. such as gases which have been heated by electrical discharge means for use in the vapor phase manufacture of oxides of titanium, iron, aluminium, silicon or zirconium and offer low capital costs combined with resistance to thermal shock.</p> |
