Sodium silicate: Cycles

A steady business shaken by Europe's gas shock

A steady business shaken by Europe's gas shock What this tab covers How its prices and margins move: past booms and busts with price levels, the spread or margin that the industry watches, the drivers of the cycle and the metrics to track.

Sodium silicate is a steady, regional business with no public price series. Prices are cost-plus and move with soda ash and energy. European producers saw costs jump with gas prices in 2022 and passed them on with a lag. Demand is defensive (detergents, paper) with growth from tyres. The best visible indicators are soda ash prices, European gas prices and the results of producers such as Qemetica and PQ.

Booms and busts

2021-2022
European gas and soda ash prices rose sharply, raising furnace costs; producers added energy surcharges (indicative).
not published for silicate; soda ash and gas price rises are covered in the soda ash tile
2023-2024
Energy costs eased and Chinese soda ash capacity grew, lowering input costs (indicative).
not published
2024-2029
Market value expected to grow from $5.50 billion to $6.83 billion, led by Asia Pacific detergents and precipitated silica (MarketsandMarkets).

What drives the cycle

Soda ash price. The largest cost item in the furnace route.
Energy prices. Furnaces burn 4-6 GJ per t; European gas spikes raise costs.
Tyre production and silica loading. Precipitated silica follows tyre output and EU tyre labelling for rolling resistance.
Detergent formulation. Powder versus liquid detergent shifts silicate demand, especially in Asia and Africa.

Metrics to track

Metric	Why it matters	Where to track it
Soda ash prices (China, US export)	Main input	SunSirs; USGS; ICIS
TTF gas price	European cost	ICE Endex
Precipitated silica capacity additions	Main demand driver	Company announcements (Evonik, Solvay, PPG, Chinese makers)
