The present invention discloses a method of manufacturing micronized sandstone obtained from ceramics or industrial wastes of ceramic manufacturing, such as white paste, natural stones or clinker, including TiO.sub.2 as bio-additive, and product obtained by the micronized sandstone thereof. The ceramics and industrial wastes of ceramic are grinded in several steps and the resultant powders are collected by means of individual filters and further combined in a nanopowder micronizer for posterior treatment, where TiO.sub.2 hydrolyzed can be optionally added. This micronized sandstone comprising the bio-additive TiO.sub.2 is used in the production of plasters, mortars, grouts and/or as additive for paints and/or epoxy enriched with TiO.sub.2. The micronized sandstone bio-additive with TiO.sub.2 can be additionally subjected to two optional embodiments of the invention: treatment with or without the use of a pigment. In order to obtain the final product that can be used in the production of blocks, floors and other products of various sizes, an agglomerating agent combined with TiO.sub.2 is added to the micronized sandstone comprising the bio-additive TiO.sub.2, either in an aqueous solution or as a dry product, optionally including colored oxides.

The present invention relates to fabricating lightweight ceramic sand as a building and construction material. More specifically it relates to a novel process of manufacturing sintered synthetic lightweight ceramic sand particulates directly from pond ash and fly ash as a secondary raw material. The said synthetic lightweight ceramic sand can be used as a building material. The novel feature of the invention is to manufacture low cost lightweight sand at high throughput to compete against the fast depleting natural sand and crushed stones.

Disclosed are a low-shrinkage, high-strength, and large ceramic plate and a manufacturing method thereof. The method comprises the following steps: (1) preparing a ceramic raw material powder; (2) subjecting an acicular wollastonite to surface coating with a silane coupling agent and to pre-dispersion with a fumed silica to obtain a pre-treated acicular wollastonite; and (3) thoroughly mixing the ceramic raw material powder and the pre-treated acicular wollastonite and granulating the resulting mixture, the amount of the pre-treated acicular wollastonite added being 10 wt % to 30 wt % of the ceramic raw material powder, and subjecting the resulting granules to dry pressing and sintering to obtain the large ceramic plate. The acicular wollastonite is incorporated into the manufacturing of the large ceramic plate to take full advantage of the reinforcing effect and low sintering shrinkage characteristics of the acicular wollastonite. The invention reduces sintering shrinkage and increases product strength.
