The invention relates to the industry of refractory materials. A chamotte for manufacturing of reractory articles contains, weight %: filling agent of zirconium dioxide, stabilized with ~10 weight % yttrium oxide – 40-45, fine-grounded component – a mix of joint grinding with grain size not less than 0.063 mm, zirconium dioxide, stabilized with yttrium oxide, monoclinic zirconium dioxide and alumina with weight part of α-AlOnot less than 85 %, at their ratio from 0.8:0.2:0.05 to 1:0.1:0.02 – 55-60. The invention allows to form refractory articles with high seeming density and high refractoriness. |
