Abstract
A method of producing inorganic fibers includes heating and melting an inorganic raw material that includes 70 wt % or more of silica and 10 wt % to 30 wt % of magnesia and calcia in total in a container to obtain a melt having a melt viscosity of 15 poise or less, supplying the melt to a rotor that rotates at an acceleration of 70 km/s2 or more, drawing the melt due to a centrifugal force caused by rotation of the rotor to obtain fibers, blowing the fibers off by blowing air around the rotor, and collecting the fibers to obtain fibers having an average fiber diameter of 5 μm or less.
