Hangarau Raraunga Hua Whakataki:
e whakaputaina te reira na roto i te tukanga niao me calcification, ki te wāhanga karaihe o γ-Al2O3 Al2O3 α- ranei. Kei te āhuatanga i te reira o te abrasion iti, tohatoha rahi matūriki kuiti (20-130μm), me conglobation pai, i te mea te ao kitea i roto i te karu. Te whānui whakamahia te reira i rite te kawe whakakōkī i roto i te ahumahi matūngahinu.
