Dry-grinding of zircon concentrate with 1% added TiO 2 gives a fine-grained powder suitable for the production of close-texture and high-density refractories. The powder for the latter should contain 70–80% fractions finer than 10μ and that for close-texture refractories at least 50–60% of these fractions. The powders can be produced by grinding in a vibro-, ball, or tube mill.
