A ceramic material having a lower melting point than the particles was interposed, and the ceramic material was once melted and then solidified to join the glass porous lightweight particles. In order to obtain a lightweight material having such a structure, the glass porous lightweight particles having internal pores are filled in a mold, and pressurized as necessary. By heating at the above temperature, the surface layer portions of the glass porous lightweight particles are fused.

It is preferable that the temperature is 30 ° C. or lower. 3
If there is a difference in melting point of 0 ° C. or more, the range of the heating temperature can be widened, and the operability is improved.

3 ) The ratio of the weight (g) of the ceramic material is 100:
600 to 100: 10 is preferred. This is because when the weight of the ceramic material exceeds 600 (g) with respect to the volume of the glass porous lightweight particles of 100 (cm 3 ), the deformation of the ceramic material increases due to the melting of the ceramic material, and the weight of the ceramic material becomes 15 (g). If less, the coating will be non-uniform. In particular, in the case of wet molding, the ratio between the volume (cm 3 ) of the glass porous lightweight particles and the weight (g) of the ceramic material is 100: 400 to 10
0: 100 is preferable, and in the case of dry molding, the ratio of the volume (cm 3 ) of the glass porous lightweight particles to the weight (g) of the ceramic material is preferably 100: 50 to 100: 200.

1 mm or more and 5 mm or less are preferable. When the thickness is less than 0.1 mm, unevenness of the coating is liable to be caused.
If the ratio exceeds, non-uniform filling is likely to occur. In this sense, the particle size of the glass porous lightweight particles is 0.15 mm.
More preferably, it is not less than 1.2 mm.
