The　foam　glass　was　produced　through　the　foaming　process,　using　waste　glass　as　the　primary　raw　material,　calcium　carbonate　which　will　break　down　into　carbon　dioxide　in　the　molten　state　at　high　temperature　as　foaming　agent,　boric　acid　as　fluxing　agent,　sodium　phosphate　as　foam　stabilizer.　With　the　aid　of　XRD,　ESEM　and　other　instruments　helping　characterize　and　analyze　the　microstructure　and　phases,　the　influences　of　sintering　temperature　on　foam　glass　were　examined　including　the　pore　structure,　apparent　density,　thermal　insulation,　etc.　The　results　demonstrated　that　the　porosity　of　foam　glass　increased　with　the　rising　of　temperature,　and　the　gas　escaped　and　the　pores　shrank　when　it　reaching　a　certain　temperature.　The　apparent　density　and　flexural　strength　displayed　the　downward　trend.　The　sample　has　relatively　optimum　properties　especially　in　thermal　insulation　at　810℃　with　evenly　distributive　moderate　aperture　whose　apparent　density　was　297.62　kg/m3,　flexural　strength　was　1.02　MPa,　volumetric　water　absorption　was　17.92%.　©　2016,　Chongqing　Functional　Materials　Periodical　Press　Co.　Ltd.　All　right　reserved.
