STRONTIUM METAPHOSPHATE C화학적 특성, 용도, 생산
개요
Strontium metaphosphate can be prepared by the solid-state reaction of metaphosphoric acid and the hydroxide, oxide or carbonate of strontium:SrCO3 + HPO3 + heat ? Sr(PO3)2 +H2O + CO2
The best temperature to use is about 600°C. Strontium metaphosphate has the CAS number of 13762-75- 9 and a density of 2.61 g/cm3. It melts at 757°C and its boiling point is 1384°C. It is somewhat soluble in water.
용도
The combination of sodium and strontium polyphosphate forms a low-melting glass with a high coefficient of thermal expansion. The melting point of the glass increases with Strontium content. This glass makes seals with low melting metals like aluminium (melting point 650 °C). Normal borosilicate glasses soften above the melting point of aluminium. This mixture is prepared by heating a mixture of diammonium phosphate, sodium carbonate, and Strontium carbonate.STRONTIUM METAPHOSPHATE 준비 용품 및 원자재
