Silica fume for interior wall brick

Silica Fume for interior wall brick: This Microsilica is commonly used in the manufacture of interior tiles to increase the glossiness of the glaze and other properties of the tiles.

Reduce the firing temperature: traditional ceramic raw materials are mainly kaolin, is a silicon-aluminium system, using high-temperature firing (1250 ~ 1350 ℃), the generation of the crystalline phase is mainly mullite. The introduction of Silica Fume For Ceramics constitutes silicon-aluminium-calcium low eutectic system, the main crystalline phase is calcium feldspar. silica fume for ceramics and kaolinite should be generated calcium feldspar temperature of 900 ~ 1000 ℃, compared with kaolinite to generate mullite reaction temperature is much lower.

Shorten the firing cycle: due to Silica fume for ceramics particles are needle-like, in the body drying and firing process, silica fume for ceramics needle-like crystals become a channel for moisture escape, so drying and firing fast, thus shortening the firing cycle, improve efficiency.

Improve the strength of the body and products: silica fume for ceramics needle-like crystals in the body was interwoven structure, silica fume for ceramics linear expansion coefficient is small, small volume contraction during firing, residual silica fume for ceramics interwoven structure, improve the mechanical strength of the body and products, which is useful for the production of high-strength ceramics.
