详细
The effect of nonisothermal heating in a high-temperature dilatometer and isothermal heating in the range 900 – 1600°C on sintering and secondary mullite formation for specimens based on composite composition HCBS, including with refractory clay additions, is studied. Maximum shrinkage values of 0.4 – 1.3% depending on composition are noted with nonisothermal heating up to 1200 – 1250°C or after isothermal firing at 1100 – 1200°C. Specimen growth index (up to 2.0 – 2.5%) after high-temperature firing depends on SiO2 content that indicates the volume of secondary mullite formed.
