Grog (clay) - Wikipedia
Grog, also known as firesand and chamotte, is a raw material usually made from crushed and ground potsherds, reintroduced into crude clay to temper it before making ceramic ware. It has a high percentage of silica and alumina. It is normally available as a powder or chippings, and is an important ingredient in Coade stone.
Chamotte for the production of ceramics and refractories - Imerys
Chamotte—also known as ‘grog’, ‘firesand’ or “fireclay”—is calcined clay containing a high proportion of alumina. It is produced by firing selected fire clays in a rotary kiln to temperatures between 1,400°C and 1,600°C, before grinding and screening to specific particle sizes.

Chamotte reduces cracking and shrinkage in ceramics - Imerys
Chamotte is calcined clay containing a high proportion of alumina. It is produced by firing selected fire clays in a rotary kiln to temperatures between 1400°C and 1600°C, before grinding and screening to specific particle sizes.
Chamotte Bricks, Characteristics of | SpringerLink
2022年10月7日 · Chamotte bricks are prepared using chamotte as aggregates and refractory clay as the binder. With an Al 2 O 3 content of 30–48%, chamotte bricks are the oldest and most widely used refractories. The raw materials are clay minerals.
Kaolin for Refractories - AIMR
AIMR’s calcined Kaolin (Chamotte) is considered an important constituent in the Alumina refractories manufacturing. Refractories are those heat-resistant materials which maintain their chemical and physical properties under thermal pressure and a high temperature (up to 3000 ° C).
Chamotte — Wikipédia
Chamotte. La chamotte, « argile réfractaire », « argile cuite » ou « tesson broyé », est une argile contenant une forte proportion d'alumine. Elle est produite à partir d'argiles réfractaires spécifiques cuites à des températures comprises entre 1 400 °C et 1 600 °C [1]. Elle est ensuite broyée et tamisée [2].
chamotte bricks is better than that of silica bricks and magnesia bricks. There also are chamotte bricks with special properties, such as low poros-ity chamotte bricks (porosity <15%) and low creep chamotte bricks (creep rate < 1% at 1100–1250 C holding for 50 h) (Fig. 1).

2013年12月13日 · Chamotte is kaolinite grade clay calcined at 1350°C to produce 38% crystalline mullite, as well as metastable cristobalite and quartz. The chemical composition of the chamotte is almost identical to that of the metakaolin used to create the geopolymer, however, its crystalline nature prevents reactivity with the caustic potassium silicate ...
Chamotte – Sibelco
Chamotte is used in pottery and sculpture to add a gritty, rustic texture called “tooth”; it also reduces shrinkage and aids even drying. This prevents defects such as cracking, crow feet patterning, and lamination. It also adds structural strength to hand-built and thrown pottery during shaping although it can diminish fired strength.
