Technical Properties & Material Specifications

Strontium has an atomic mass of approximately 87.62 u and a density of about 2.64 g/cm³. Its melting point is around 777 °C and its boiling point is approximately 1382 °C. A particularly important property is its high chemical reactivity. Strontium reacts with oxygen and moisture, forming strontium oxide and strontium hydroxide, among other compounds. Therefore, metallic strontium is typically stored under suitable protective conditions. Strontium is a relatively soft alkaline earth metal and can be machined under appropriate conditions. Due to its reactivity, it is frequently processed under a protective atmosphere. In chemical compounds, strontium occurs almost exclusively in the +2 oxidation state. Strontium compounds possess varied technical properties and are used in numerous industrial sectors. Another characteristic feature is the intense red flame coloration of certain strontium compounds, which is utilized particularly in pyrotechnics. In metallurgy, strontium is used as an alloying additive. Particularly in aluminum-silicon casting alloys, strontium can influence the formation of the silicon structure and thereby improve the mechanical properties of suitable cast materials. In the chemical industry, metallic strontium serves as a starting material for the production of various strontium compounds. In pyrotechnics, strontium compounds are used to generate intense red color effects, with metallic strontium serving as a precursor for such compounds. In materials research, strontium is employed in the development of special alloys and functional materials. Furthermore, strontium is important for the production of specific metallurgical intermediates and specialty materials. Outstanding material properties include an alkaline earth metal with high chemical reactivity, a low density of approx. 2.64 g/cm³, a melting point of approx. 777 °C, and an atomic.

How Is the Purchase Price Determined?

A fair valuation when you sell Strontium (Sr) is based on verifiable analytical methods and current global market quotations:

• X-Ray Fluorescence Analysis (XRF): Precise laboratory determination of the exact purity and alloying elements.
• Purity & Condition: Dry, clean, and well-segregated batches achieve the highest recovery rates.
• Batch Weight: Settlement is based on calibrated net weight measurement without arbitrary quantity surcharges.
• Market Benchmarks: Continuous alignment with international metal quotations (LME, Fastmarkets).
