Abstract: The non-flammable phenolic resin foam with plane surface and high fire resistance in this invention is produced by mixing 30 to 100 parts by weight of resol type phenolic resin, 0.3 to 10 parts by weight of foaming agent, 10 to 50 parts by weight of curing agent, 30 to 800 parts by weight of ceramic micro-hollow particles (compression strength of 600 kgf/cm.sup.2 or more, bulk density of 0.3 to 0.5 g/cm.sup.3 and melting point of 1500.degree. C. or more), 2 to 250 parts by weight of inorganic filling agent, 40 to 250 parts by weight of aluminum hydroxide with water, press molding and heating for curing.

Abstract: In the waterproof lightweight grain-tone decorative panel of the present invention, a waterproof grain-tone paint layer is formed on the surface of a lightweight board such as a plastic foaming board and the like. In the layer, a micro-hollow fine ceramic particle of a waterproof pressure strength of 600 kgf/cm.sup.2 or more and a crushed natural stone particle are bound with a synthetic resin waterproof binder.

Abstract: The expanded ceramic molded plate of the present invention is produced by point joining together ceramic micro-hollow particles of a compact strength of 600 kgf/cm.sup.2 or more, a bulk density of 0.3 to 0.5 g/cm.sup.3, and a melting point of 1500.degree. C. or more, at the tangent points thereof, by means of an inorganic binder, so that air flow pores in the shape of a capillary tube can be retained among the individual micro-hollow particles.
