    Abstract: This invention relates to a glass-ceramic material and its production method wherein glass ceramics having low expansion coefficient are produced ecologically and whereby said method comprises the steps of raw material batch preparation (101), melting (102), batch compensation to final composition (103), refining of the gas bubbles (104), shaping process (105) and ceramization (106). Preferably, the glass-ceramic comprises in wt %: 60-70 SiO2, 15-25 AI2O3, 0.5-5 B2O3, 3-8 Li2O, 0.5-2 Na2O, 0.1-0.8 K2O, 0.1-1.5 BaO, 0-0.5 CaO, 1-2.5 ZnO, 1-4 TiO2, 1-4 ZrO2, 0.1-2.5 P2O5, 0-0.5 MgO. The batch compensation step (103) consists in adding 0.5-5 wt % B2O3 and 0.1-2.5 wt % P2O5 during the melting process (102). Instead of oxide raw materials, carbonates (e.g. Li2CO3), nitrates (e.g. KNO3), or sulphates are used.

    Abstract translation: 本发明涉及一种玻璃陶瓷材料及其制造方法,其中具有低膨胀系数的玻璃陶瓷是生态生产的,其中所述方法包括以下步骤:原料分批制备(101),熔融(102),最终组合物 103),气泡(104)的精制,成型工艺(105)和陶瓷化(106)。 优选地,玻璃陶瓷包含重量%:60-70SiO 2,15-25Al 2 O 3,0.5-5B 2 O 3,3-8 Li 2 O,0.5-2 Na 2 O,0.1-0.8K 2 O,0.1-1.5 BaO,0-0.5 CaO ,1-2.5 ZnO,1-4TiO 2,1-4 ZrO 2,0.1-2.5P 2 O 5,0-0.5 MgO。 批量补偿步骤(103)包括在熔融过程(102)期间添加0.5-5重量%的B2O3和0.1-2.5重量%的P2O5。 代替氧化物原料,使用碳酸盐(例如Li 2 CO 3),硝酸盐(例如KNO 3)或硫酸盐。
