Abstract—In this paper we present the results of analysis of
the scientific and technical literature concerning the ways of
obtaining wollastonite from various calcium and
silicon-containing technogenic wastes accumulated on the
territory of the Russian Federation. We proposed a method for
producing autoclave needle-like wollastonite from waste of boric
acid (borogipsa) containing both calcium and silicon
constituents. The phase composition and morphology of the
products autoclaving borogipsa were studied. It is found that the
initial product has a crystalline phase of unreacted calcium
sulfate anhydrous, tobermorite and xonotlite. After firing at
1000 °C, the amorphous calcium hydrosilicates are converted to
a crystalline phase of wollastonite triclinic modification. The
effect of firing temperature on phase composition and
morphology of the compounds obtained by autoclave treatment
were described. It is shown that with increase of the firing
temperature up to 1200 °C along with a phase change, the
composition variation of the particle morphology occurs. It is
found that the processing borogipsa to obtain needle-like
wollastonite recommended firing temperature should not exceed
1000 °C.
Index Terms—Industrial waste, wollastonite, borogypsum.
