Undensified Silica Fume ( Microsilica ) ( Grey ) for Refractory Cast Fused Cast and Sintered Refractories for Glass furnaces 

The Applications Of Silica Fume ( Microsilica ) ( Grey ) In Refractory Materials

Silica fume is mainly used to improve refractory materials for over forty years. Silica fume using in refractory materials has many features as following:

  • Silica fume can increase the liquidity of pouring type of refractory materials, reduce water consumption and make it easy to shape and improve production efficiency greatly.
  • Because of its ultra-structure of filler, the density of refractory material and strength will increase significantly;
  • Silica fume has high activity, under the premise of existence of Al2O3 ingredients, it is easy to generate the mullite phase to make the high temperature strength and thermal shock resistance increase greatly.
  • Silica fume has strong hydrophilic. Adding water, it can make stronger cohesion in refractory material in order to improve the performance of high temperature resistance of refractory and prolong the service life of refractory products.

Refractory material usually uses unencrypted micro silicon powder. At present, besides in casting refractory material widely using, unencrypted micro silicon is applied extensively in the fused and sintered refractories. Such as low cement castable, developed in the seventy’s, is a new type of high performance refractory castable, which is successfully developed by France first. Therefore, silica fume is widely applied in various industrial high temperature furnace with good technical and economic effect.

Low cement castable and ordinary castable both use calcium aluminate cement. But adding silica fume and high efficiency water reducing agent, it can not only save expensive aluminate cement 50-70% but also improve the cement performance. Silica fume has double applications in the new castable. Because of the size of silica fume is very small, and an important feature of silica fume can reduce the cement content in the refractory casting material.

 

Silica fume is widely used in refractory industry. Refractory raw material can be instead of pure aluminium oxide mud as refractor material; Used as an additive to join in the production of amorphous and shaped refractory products, silica fume can improve strength and increase the high temperature performance. In addition, it is applied in the ladle as a whole as condensation agent. According to the data indicate, the low cement castable with silica fume has been widely applied in coke oven, the sintering, steel-making, steel rolling, nonferrous metallurgy, petroleum as well as chemical, cement, glass ceramics and power generation industry

FormulaSiO2

Microsilica ( Grey ) is a mineral admixture composed of very fine solid glassy spheres of silicon d i oxide (SiO2). Each particles are less than 1 micron in diameter, generally 50 to 100 times finer than average cement or fly ash particles. Frequently called condensed silica fume, microsilica is a by- product of the industrial manufacture of ferro silicon and metallic silicon in high-temperature electric arc furnaces. The ferrosilicon or silicon product is draw n off as a liquid from the bottom of the furnace. Vaporizing from the 2000-degree-C furnace bed is oxidized, and as it cools condenses into particles which are trapped in huge cloth bags. Processing the condensed fume to remove impurities and control particle size yields microsilica. It helps in compressive strength, bond strength, and abrasion resistance. Addition of silica fume also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways and runways (because of the use of deicing salts) and saltwater bridges. Silica fume reduces bleeding significantly because the free water is consumed in wetting of the large surface area of the silica fume and hence the free water left in the mix for bleeding also decreases. Silica fume also blocks the pores in the fresh concrete so water within the concrete is not allowed to come to the surface.

White Microsilica ( Silica Fume ) – the Ultimate Pozzolan We supply Micro Silica (also known as silica fume) products to the following industries :- White Microsilica fume (powdery) is a very rare micro silicon powder. It is very strict on the raw material and production process and it can be used in superfine fillers with high whiteness requirements, such as grout, sealant, repair agent and so on. White Microsilica ( Silica Fume ) improves the properties of both fresh and hardened concrete. The most important property is the permeability, Lower the ingress of movement of water or chemicals; lower the adverse reactions such as sulfate attack, The reaction between silica fume and the calcium hydroxide, released as the cement hydrates, provides a dense impermeable pore structure. The temperature of the white microsilica fume is 1800 degrees, higher than the ordinary microsilica fume, so in the refractory industry, white micro silicon powder is more popular. Improve the mechanical performances of concrete. The Silica fume reacts with the cement paste to form additional strong Calcium Silicate Hydrate (CSH) providing higher strength. Silica fume reduces bleeding and enhances the cement paste bond to the aggregates. Thanks to its pozzolanic effect (reaction with Ca(OH)2 ), and therefore to the strength improvement.
