Abstract

The invention discloses a ceramic ferrosilicon red material prepared with red-bed mudstones as a main raw material. The ceramic ferrosilicon red material is prepared by the following steps: with red-bed mudstones and ferric oxide as raw materials, adding a mineralizer, and carrying out coarse crushing, burdening, mixing, sieving, mechanochemistry ball milling and roasting to obtain a product. By adopting the preparation method of the ceramic ferrosilicon red material, with cheap red-bed mudstones as the main raw material, only a small quantity of Fe2O3 chemical material needs to be added, and the ceramic ferrosilicon red material with good color generation is prepared by combining a mechanochemistry method; and compared with the traditional preparation method of a ferrosilicon red material, the preparation method of the ceramic ferrosilicon red material has the advantages of simpleness in process, no pollution to the environment, high yield, little energy consumption, lower cost, pure color development and the like and has a wide market prospect.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and in particular relates to a ceramic ferrosilicon red material prepared from red bed mudstone as a main raw material. Background technique [0002] Ferrosilicon red material is a ceramic-wrapped color material that can present a bright desert red tone in the green body and is resistant to high temperatures. Its main chemical composition is SiO 2 It acts as a carrier in the color material, similar to ZrSiO in zirconium iron red material 4 The role of crystals. It is SiO 2 As the wrapping phase, SiO is used 2 Microcrystalline phase and SiO 2 Glass relative colorant Fe 2 o 3 Wrapped so as to play a role in high temperature stability. while Fe 2 o 3 As a colorant, it is the main component of the coloring of the pigment. The main components of natural ferrosilicon red material are silicon and iron, and also contain a small amount of aluminum. Its coloring mechani...
