production process of gypsum board Introduction

11.16 Gypsum Manufacturing - US EPA
To produce plasters or wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4½H2O), commonly called stucco. A flow diagram for a typical gypsum process producing both crude and finished gypsum products is shown in Figure 11.16-1. In this process gypsum is crushed, dried, ground, and calcined.

Gypsum - Wikipedia
A new study has suggested that the formation of gypsum starts as tiny crystals of a mineral called bassanite (CaSO 4 · 1 ⁄ 2 H 2 O). This process occurs via a three-stage pathway: homogeneous nucleation of nanocrystalline bassanite; self-assembly of bassanite into aggregates, and; transformation of bassanite into gypsum.

Gypsum - an overview | ScienceDirect Topics
Gypsum boards or plasterboards are typical materials used to build light walls. The production process is based on gypsum hydration technology. At the very beginning of the process dehydrated calcium sulfate (gypsum) is converted into CaSO 4 ·0.5H 2 O by heating. Once dehydrated, gypsum is mixed with water, starch, a foaming agent, and other additives.
