Basic Info

What is Potassium Silicate?

Potassium silicate is also referred to as potassium metasilicate. Separated right into 3 kinds:

  1. K2SiO3 = 154.29, anemic crystal, typically turquoise block or glazed solid. The melting point is 976 ° C. Soluble in water, conveniently soluble in hot water or under pressure, the liquid remedy is alkaline, insoluble in ethanol. In case of acid, it will certainly decompose and also separate out silicic acid gel. It soaks up water and deliquescence in the air.
  2. K2Si2O5=214.37, colorless orthorhombic crystal. The relative thickness is 2.456 (25/4 ° C), and also the melting point is 1015 ± 10 ° C.
  3. K2Si4O9 · WATER=352.56, white orthorhombic crystal. The family member thickness is 2.417, and also it will disintegrate when heated to 400 ° C. Soluble in water, insoluble in ethanol.

It is made by thawing potassium carbonate or potassium hydroxide and also quartz sand at heat. Potassium silicate is hygroscopic and has a strong alkaline response. Potassium silicate is fairly simple to disintegrate in acidic environment as well as speed up silica. Potassium silicate is usually utilized in the manufacture of welding electrodes, welding electrodes, barrel dyes, fire resistants, fluorescent display finishing layers and soap fillers, etc. Therefore, potassium silicate has a wide range of uses. The kinds of aspects consisted of in potassium silicate are relatively close to potassium feldspar, so it is of excellent relevance to examine exactly how to utilize potassium feldspar to disintegrate as well as prepare potassium silicate.

Potassium Silicate Uses

  • Fireproofing of wood products
    Soaking wood with potassium silicate solution is a simple and low-cost method, which can make the wood products of houses safe and fireproof. Wood products are first soaked with diluted, near-neutral potassium silicate solution. After drying, one or two layers of solution with higher concentration are usually applied.
  • Horticulture
    In horticulture, potassium silicate is utilized as a soluble source of potassium as well as silicon dioxide. It makes the development tool extra alkaline.
    It is also utilized as a supplement (utilized with usual fertilizers) to get several benefits of increasing the schedule of silicon substances. Silicon-containing compounds are useful to plants and also are used to sustain plants. The stems become thicker, the plants become extra drought-resistant as well as immune to withering, and also the plants grow larger leaves and fruits (since the stems can sustain even more weight). The thicker cell wall of plants likewise gives added mechanical resistance to sucking pests (such as crawler) as well as numerous pathogenic fungis (such as fine-grained mildew).
  • Industrial use
    Some metal cleansing formulations use potassium silicate, which can likewise be utilized as a rust prevention. It also has many uses in the manufacture of welding poles as well as even cosmetics.

Application of Potassium Silicate

Production Method of Potassium Silicate

Melting technique Mix silica sand as well as caustic potash in a certain proportion and put them right into the melting heating system, warm them with heavy oil or electrical energy to 1200-1400 ° C, when an entirely molten transparent body is developed, release it from the heating system, trendy and also solidify, and then put it right into the autoclave, Dissolved by pressurized heavy steam (0.2 MPa). The solution is delegated clear up to get rid of pollutants, and the clarified option is concentrated to acquire the finished item of potassium silicate. Its
