Micro Silica

turkey micro silica


Micro silica or silica fume includes silicon dioxide is very reactive mineral additive. It uses in wide areas such as drilling mud, construction, electrical and furnaces during reduction of very pure quartz.Silica cools so rapidly and forms extremely fine in a minute. It used as a filler or extender in rubber or plastic industry. It is weighting agent in down hole and also decreases permeability. In construction it improves the strong and permeability of roofing pane

A lot of transportation agencies are using this material in their concrete for construction of new bridges or rehabilitation of existing structures. It is for use in concrete is available in wet or dry forms. It is usually added during production at a plant. These compositions concrete has been successfully produced in both central-mix and dry-batch plants.


Introduction to Micro Silica

Micro silica, also known as silica fume or condensed silica fume, is a byproduct of the production of silicon metal or ferrosilicon alloys. It is composed of ultrafine particles of silicon dioxide, typically with diameters ranging from 0.1 to 0.3 micrometers. Despite its diminutive size, packs a punch when it comes to improving the properties of various materials.

Role of Micro Silica in Drilling Mud

In the realm of drilling operations, it serves as a game-changer, imparting several key benefits to drilling mud:

Enhanced Fluid Rheology

The Micro silica acts as a rheology modifier, influencing the flow behavior and viscosity of drilling mud. By optimizing fluid rheology, it helps maintain wellbore stability and facilitates efficient drilling performance.

Improved Fluid Loss Control

One of the primary challenges in drilling operations is fluid loss into porous formations. Silica’s ultrafine particles penetrate deep into formation pores, creating a barrier that mitigates fluid loss and enhances wellbore integrity.

Increased Compressive Strength

In cementitious applications within drilling mud, micro silica functions as a pozzolanic additive, reacting with calcium hydroxide to form additional binding compounds. This leads to increased compressive strength, crucial for cementing well casings and preventing formation collapse.

pH Stabilization

Our Micro silica’s alkaline nature helps stabilize the pH of drilling mud, preventing corrosive reactions and preserving the integrity of downhole equipment.

Applications Beyond Drilling Mud

Beyond its role in drilling operations, micro silica finds diverse applications across various industries:

Concrete Reinforcement

In the construction industry, micro silica is extensively used as a supplementary cementitious material in concrete mixtures. Its ultrafine particles fill gaps between cement grains, enhancing packing density and reducing permeability. This results in concrete with higher strength, durability, and resistance to chemical attack.

Refractory Materials

Turkey micro silica’s high silica content and fine particle size make it an ideal additive in refractory materials used in high-temperature applications. It improves the packing density of refractory castables, enhancing their thermal shock resistance and erosion resistance.

Polymer Composites

In the realm of polymer composites, micro silica acts as a filler material, improving the mechanical properties and dimensional stability of composite products. It enhances the modulus of elasticity, tensile strength, and impact resistance of polymer matrices, making them suitable for a wide range of applications.
