| High
Precision and High Density Aluminum Silicate Board
Production Technique
The high precision and high density
aluminum silicate board is manufacturing with semi-finished
aluminum silicate felt with addition of a given proportion
of cementing agent by shape setting through compression
and solidification and lengthwise and crosswise cutting.
