Sodium silicate, dissolved in water through the hydrothermal method until it becomes a clear, homogeneous liquid that is either colorless or gray, is also known as Waterglass. This term refers to glass that can dissolve in water

Solid sodium silicate is produced by mixing sand, which is a source of silica (SiO2), with soda ash (Na2CO3) to achieve a uniform distribution. This mixture is then melted in a high-temperature furnace.

Sodium Silicate is produced through a relatively straightforward process. It begins with mixing sand and soda ash, which is then fed into a high-temperature furnace. This produces a molten liquid resembling lava. The molten material is then poured into molds and allowed to cool, resulting in solid sodium silicate, also known as Cullet. For liquid sodium silicate, the solid Cullet is placed in a pressure-controlled vessel to be melted and adjusted to the desired mole ratio.
Eastern Silicate Co., Ltd. has sufficient production capacity to meet the demands of customers across all industry sectors. Our production capacity is divided as follows: Sodium Silicate Solid is split into two products, Sodium Silicate Solid 2 Mole and Sodium Silicate Solid 3 Mole with a combined production capacity of 5,000 tons per month.
We also have plans to expand our production capacity in the future. For Sodium Silicate Liquid which is also divided into two main product groups, Sodium Silicate 2 Mole and 3 Mole, the production capacity for both main groups ranges from 12,000 to 15,000 tons per month.
"Eastern Silicate Co., Ltd. is committed to product development while also taking care of the environment. We have a team of experts in sodium silicate and are equipped with comprehensive and modern research tools and equipment."
