The present invention relates to a kind of talcum building ceramic brick and manufacture method thereof, the chemical group of this porcelain becomes: 55 ~ 65%SiO 2 、10~25%Al 2 O 3 、10~25%MgO、1~4%K 2 O、0.3~1.5%Na 2 O, 1 ~ 5%CaO; Composition of raw materials used is: talcum 35 ~ 75%(wherein: raw talcum: burn talcum=0.1 ~ 1), feldspar 8 ~ 35%, kaolin 15 ~ 35%, wollastonite 0 ~ 5%, aluminum oxide powder 2 ~ 10%; Adopting the general firing process of building ceramic tiles, its firing temperature is: 1100 ~ 1250 DEG C. The present invention adopts the raw talcum of part and aluminum oxide powder, effectively overcomes the shortcoming that steatite ceramic processability is poor, firing range is narrow, is easy to apply. |
