Metastable Rubidium Aluminum Silicate with a Hexagonal Sheet Structure.
A compound of composition RbAlSi(3)O(8), with a structure of double sheets of silica-alumina tetrahedra with common apices held together by rubidium ions in 12-fold coordination, may be crystallized from a melt by rapid cooling. The compound is an analog of the metastable forms of the calcium, barium, strontium, and lead feldspars.
