| Preliminary Reseach on Uses of Magnesiun Clay in Basic Refractory Industry |
| In this scientific research project, the main procedure is to make sintering test between magnesiun clay and peridotite or slag of magnesia bricks bonded by tar, in a box_type furnace at 1200～1250 ℃ The author determined physical propertles and mineral components for raw materials, samples of sintering test and five kinds of products The results show that most minerals of products are magnesium-rich minerals with high melting point including lnherited or neoformd forsterite and periclase, small amounts of monticellite and oakermerte, and trace di_calcium silicate The No 2 product contains more clino_enstatite transformed from talc or sepiolite and its melting point is lorwer than that of others Although the instruments are simple and technique of sintering lags bebind, the author still has achieved a remarkale progress The reason of the achievement is clear now To select proper raw materials and to make up prescription well may be the first step towards the achievement, whereas coordination between lean and plastic materials is reappearance of traditional experience In this occasion, magnesim clay as a bonding clay plays an important role The fast determination of melting point for sintering samples by means of oxygen_coal gas flame is a test to be full of significance. |
