| 摘要 |
<p>The invention relates to a silicate compound having at least one alkaline oxide and silicon dioxide-containing amorphous binder matrix and also containing oxides from the aluminium, calcium,titanium, magnesium, zirconium and/or boric oxide group. To provide a silicate compound which is suitable for both making a moulding and coating a substrate, resistant to effects like weathering, especially through alternate frost and thaw, and attack by acids, lyes or fouling, it is proposed that the amorphous binder matrix contain 4 to 25 mol silicon dioxide per mol alkaline oxide, the alkaline oxide be lithium, sodium and/or potassium oxide and the amorphous binder matrix also contain up to 80 mol aluminium oxide and/or up to 45 mol calcium, titanium, zirconium and/or boric oxide evently distributed per 100 mol silicon dioxide.</p> |
