Silicone is a milky white colloidal solution which has a diameter of between a few and several hundred nanometres. It is non-flammable, non-explosive and non-toxic. The ions on the surface of the silica particles are of the water table type and are hydrophilic because they are covered by water molecules. It is not well soluble with organic matter, but is soluble in alcohols, acetone and other organic solvents mixed with water in any proportion. Also soluble in hydrofluoric acid and sodium hydroxide solution, insoluble in other inorganic acids.
The silica gel is made by diluting water glass and sulphuric acid to a certain concentration and then neutralising the reaction to form a hydrogel, which is aged, washed, homogenised with additives, spray dried, air crushed and dried to produce a micro-fine silica gel. This method is known as the sulphuric acid method. It has several applications. Silica gel is a good inorganic binder used in the precision casting industry for high shell strength, high accuracy of castings, good finish, small deformation, work safety and as an adhesive for refractory and other materials when roasting at high temperatures. It can prevent oxidation of certain products. It can also be used as a matching material for paints (water-based paints for interior and exterior walls) to improve bonding, fastness, abrasion resistance and pollution resistance. As a treatment agent for synthetic fibres to improve the coefficient of friction of the fibres. As sizing agent for warp yarns in the wool spinning industry to improve spinnability, handedness, reduce flying hair and head breakage, and can increase yield. Used in the paper industry to improve paper smoothness and paper strength. Also used as a finishing agent for electronic materials mainly using ion exchange method to produce silica sols. The diluted water glass is filtered to remove impurities after cation exchange, anion exchange, pH adjustment, and concentrated by evaporation or ultrafiltration to obtain silica gel.
It can be divided into four categories, of which basic silica is a colloidal solution and has a pH in the range of 9-10. The molecular size of its solution is different from that of water and water does not mix with each other. Acid silica is also a colloidal solution and has a pH in the range of 2-4. The molecular size of the solution is different from that of water, which does not mix with each other. The modified silicone sol has special surface electrical properties due to changes in surface structure, higher product stability and stronger bonding ability. Ordinary silica gel is an ultra-fine amorphous, non-porous, usually spherical suspension of silica gel particles in a liquid.

Market Analysis and Forecasting
With the development of economy and industrial technology, the production technology of calixarene is gradually stable, and the production capacity of the industry is gradually increasing. Colloidal Silica has a potential consumer market in these countries with the continued development and promotion of downstream applications. Europe is the largest market for Colloidal Silica, with advanced research and development technologies and products with good purity and quality. As an economically developed region, the United States has diversified distribution channels and high-end research and technology. With the continuous development of economy and industry, the Asia-Pacific region has developed rapidly in the Colloidal Silica market, the industry chain has gradually improved, and industry technology is constantly evolving. This is a potential consumer market.
According to our research, the India Colloidal Silica market has a total sales value of 687.44 MUSD back in 2013, and increased to 862.62 M USD in 2018. We made a series of functional
calculation and deduced the past 5 year’s data with scientific model. Finally, we made the prediction that the value of Colloidal Silica markets can be 1008.78 M USD by 2023. The CAGR of Colloidal Silica is 5.30% from 2016 to 2022. Europe was the largest revenue market with a market share of 31.11% in 2013 and 29.87% in 2018. North America ranked the second market with the market share of 27.63% in 2017.
Colloidal Silica sale companies in India are mainly from North America and Europe; the industry concentrate rate is not high. The top three companies are AkzoNobel, Grace and Guangdong Well-Silicasol with the revenue market share of 11.89%, 10.88%, and 7.28% in 2017.
Colloidal Silica is mainly driven by the downstream market, especially the rapid development of the industry, which brings a large potential market for Colloidal Silica industry. Although sales of Colloidal Silica brought some opportunities, the study group recommends the new entrants who has not industry chain advantage and accurate positioning of the downstream segments do not enter into the Colloidal Silica field. What is more, the company in this industry should pay attention to their R&D, keep on launching new product, keep on innovation and improving services, then they may get the competition advantage, and get a bigger market share.
Colloidal Silica Labour Costs
During most of the post-crisis period global wage growth was driven to a large degree by relatively strong wage growth in emerging and developing countries in Asia and the Pacific, most notably in China, as well as in some other developing countries and regions. More recently, this trend has slowed or reversed. Among emerging and developing G20 countries real wage growth fell from 6.6 per cent in 2012 to 2.5 per cent in 2015. Looking at regional wage growth, our research shows that in 2015 real wage growth remained at a relatively robust 4.0 per cent in Asia, declined to 3.4 per cent in Central and Western Asia, and was tentatively estimated at 2.1 per cent in the Arab States and at 2.0 per cent in Africa. In 2015, real wages dropped by 1.3 per cent in Latin America and the Caribbean (mostly due to falling wages in Brazil), and by 5.2 per cent in Eastern Europe (mostly dueto falling wages in the Russian Federation and Ukraine).
In contrast, wage growth increased in the developed countries. Among developed G20 countries, real wage growth went from 0.2 per cent in 2012 to 1.7 per cent in 2015, the highest rate of the last ten years. In 2015, real wage growth rose to 2.2 per cent in the United States, 1.5 per cent in Northern, Southern and Western Europe, and 1.9 per cent in the countries of the European Union (EU). Faster wage growth in the United States and Germany explains an important part of these trends. It is as yet unclear whether such wage growth will be sustained into the future or whether developed countries will return to their previous pattern of wage stagnation. In an economic context in which risks of deflation have increased in many countries, falling wages could themselves become an important risk factor, potentially leading to deflationary wage–price spirals.
Globally, the recovery in Northern America and some European countries was not sufficient to offset the decline in emerging and developing economies. The lower differential in wage growth between developed and developing countries also implies a slowdown in the process of wage convergence between the two groups of countries.
