Product Description


Why use silicon microsilica powder?

Microsilica powder can effectively prevent accidents caused by the fluctuation of quality of micro-silica powder in the production process, and reduce the quality accidents such as scrapping and discontinuous production caused by unstable micro-silica powder quality.


Microsilica powder can bring more stable quality to your products, and at the same time greatly reduce the construction difficulties caused by problems such as excessive or too low condensation of castables during construction, and poor liquidity, and even lead to major engineering accidents, etc. The probability of occurrence of the problem, to ensure the quality of construction.


Microsilica powder can reduce the quality problem of unshaped refractory products in use, avoid accidents such as reduced service life and excessive damage due to the quality problems of silicon micro-powder during use, and can effectively improve the castables when used together with other high-grade raw materials. High temperature performance and longevity.

Winitoor information


Quanzhou Winitoor Industrial Co.,Ltd has been in microsilica(a powder),mainly

for concrete and refactory since 2004.


Our standard products are densified microsilica from SiO2 85% to 94%,mostly used

type is 85%SiO2 and 92%SiO2;

undensified microsilica for refractory from SiO2 92% to 97% SiO2,mostly used type is 94%

SiO2 and 96% SiO2,97% SiO2 is very less capacity for microsilica suppliers.


We have exported thousand tons of densified and undensified microsilica to different countries.

Our quality is under control of the ISO 9001 certificate and meeting the standard of ASTM C1240

with a third-party test quality guaranteed.

Besides,we have a well-conditioned warehouse to store our microsilica to keep a stable quality and

keep a enough capacity for our customers.

The 12th India International Refractory Conference and Exhibition in 2018
Exhibition time: March 07-09, March 2018
Venue: New Delhi, India
Holding period: two years
Organizer: Indian Society of Refractories

IRMA (India Refractory Association) is a consortium of Indian refractory industries that provides design, construction, installation and maintenance services in areas such as steel production, non-ferrous metallurgy, cement, glass, ceramics, etc., and is committed to saving costs and Provide efficiency and increase industrial added value. Its organization of refractory exhibitions and conferences is a local professional, important industry event in India.
  IREFCON -2018 is the world's second largest refractory industry event, the 12th year of the 12th, providing an important trading platform for refractory production and consumers in India and around the world. In addition to manufacturers and consumers, a large number of raw material suppliers, equipment manufacturers, test equipment, research and development institutions, design consulting, etc., will participate in the project. The 16-year exhibition was held in Hyderabad with a total of over 500 registered representatives. World industry giants Elkem, Velco GmbH, etc. all participated in the project.
[India refractory market background]
Based on India's backward infrastructure, the new Indian government will invest heavily in and improve the vast infrastructure design network to drive demand for bulk products such as cement, steel and glass, so that India will become an important refractory demand country in the world.
In 2014, India's total steel output was 86 million tons, second only to China, Japan and the United States, ranking fourth in the world. It is estimated that by 2020, steel production needs to reach 130 million tons to meet market demand. India's cement production in 2014 was 280 million tons, second only to China in the world. Huge market demand will also drive demand for refractory materials.
