High　alkali　aluminosilicate　glass　batches　were　prepared　by　five　different　raw　materials,　reaction　heat　of　which　in　melting　process　was　studied　by　means　of　DSC　thermal　analysis　method.　The　results　show　that　reaction　heat　of　batches　in　the　heating　process　of　25-1600　degrees　C　exists　a　significant　difference,　and　which　is　among　4396.38　J/g　-5311.14　J/g,　moreover　the　least　is　the　batches　using　petalite,　while　the　most　is　spodumene.　In　the　whole　heating　process,　380-800　degrees　C　is　carbonate　decomposition　stage,　which　accounts　for　42-46%　of　the　total　absorbed　heat;　and　800-1200　degrees　C　is　silicate　reaction　stage,　40-50%;　and　1200-1600　degrees　C　is　glass　clarify　and　homogenization　phase,　6%-16%.　Therefore,　carbonate　decomposition　and　silicate　reaction　is　the　main　part　of　batches　heat　consumption,　the　optimization　scheme　for　materials　has　a　significant　effect　on　energy　saving　and　emission　reduction.
